So the SDs just left. It's a little past 22 and they stayed for a few hours. It wasn't bad-they were not disrespectful,they did not cause drama or make scenes,but they were really cold.

Before the issues, their relationship with BF was great. They would joke,tell him stuff that happened at school and outside,talk about friends, discussed stuff that happens in the world,events, just everything.It was a friendly relationshpip,but at the time there was no disrespect or anything. They were friendly, close and in a good relationship but there was a lot of respect too and it was all great.

Then since there were problems,they have been disrespectful, rude, mean, and said & did things just to annoy BF ,hurt him, and make him leave me which they were pretty close to doing.

But BM helped,took SDs out with me and her,I suppose she also talked to them about their behaviour,and she also talked to them about coming to our place,so it got better.
But now they were polite - too polite, may I say. Just awkwardly proper.

For example,before the issues about me started, it would be like this : -EXAMPLE-

BF: Do you want pancakes or a sandwich?
SD(both of them would speak in a friendly tone ofc): pancakes, thanks dad, are you having them too? do you want me to make the mixture?
BF would refuse ,but theyd'd at least bring some things from the pantry. and it'd be great.

but now it was like this.

BF: Would you like to eat something?
SD14: No,but thank you for the offer.
BF: Are you sure? Aren't you hungry? (BM brought them over and said that they didn't eat so she recommended that if we want we can make something together since SDs both enjoy cooking and she thought it may help us bond,and they do love to cook, i know because they always wanted to cook something before when there were no problems)
SD14: I am a bit hungry, thank you for the concern. But I don't really feel hungry enough to eat right now, maybe later. Thank you anyway. If you're having dinner, enjoy your meal. If you want me to do something tell me.

BF was a bit weirded out by this because...wtf,it's like she's talking to a stranger or something

So when SD17 got in the room (she was in the bathroom then went to change), he asked her is she hungry and does she want to eat, she said :"I am quite hungry. I would like to eat something, yes. Thank you." So he asked what would she like, she said. "I wouldn't want you to have to bother too much with it, so whatever is convenient for you to make now is acceptable." so he said she can choose. and she said "If it's acceptable, I'd like some macaroni. If no, that is okay, I will have what you can make." so he said "no problem, I'll make macaroni." she said "Thank you for making the meal, do you want me to help with it?" he refused,thanked her, and I could see that he had no idea what's going on.

I went into the kitchen to help BF we called them to join us in there,so they came and sat there. SD14 decided she'll eat too. We asked them a bit about their day,etc. and it went like this:

BF: How was your day?
SD17: It was great, thank you for asking. How was yours?
BF: Great too. So how are your grades?
SD14: Good, I have all 5s. (5 is like an A grade)
SD17: I have two Bs though. (4 is like
Both then thanked him for his concern again. (WTF he's their father,i don't think they should be thanking him for caring about their grades but whatever..)
BF: So what are your plans for New Year's eve?
SD17: I'm going to a party at my best friend's.
SD14: Best friend rented a place with her group of friends, so we're all gonna be there. What are your plans?
We told them, so they said : "Very nice, have a good time."
I asked did they plan the outfits,and they were a bit more ready to talk about that,they told me what they are going to wear and asked what I was planning to wear. I told them and they said they like dresses like that but they prefer dark blue over light blue though they think light blue will look good on me. Well THAT was a shock. But I was really happy to hear that! And not because of looking good,but because of hearing a nice comment from them. I know it maybe wasn't sincere,but it was just nice to have them be nice.

We tried talking with them more but they'd answer very simply and it was very hard to keep the conversation,basically the outfit thing was the best part of it lol

So when we finished making the food, they thanked politely AGAIN, and didn't say anything untill they were done with the food.

SD14: Thank you for the meal, it was delicious.
SD17: Yes, thank you. We will wash the dishes now.

So I wanted to wash them, but they jumped from the table before I even got the chance to offer,and washed the dishes.
Then they went to the living room. They seemed to be getting a bit nervous,so we didn't insist on anything, we asked if there's something they'd like to do,they said "Nothing in particular, it's okay. " I said that if they think of something, they can tell us and they said "Thank you, we will. "
SD14 asked if we want her to do something in the house,we said no and thanked her. We were shocked by that since she never does anything unelss she's home alone. (she can do everything even better than most adults,just doesn't want to if there's someone else who's gonna do it)
So then, SD17: "This was a very nice visit, thank you father, thank you Vikki. If it is not a problem, we would like to go home now. We are a bit tired."
So we thanked them too,and offered to drive them home, but they said they'll walk. BF insisted but they still refused. So they walked out. They said, "Good bye, thank you", and that was it.

Bf is nervous and concerned, even though happy they at least came to our place. All that they said was pretty cold - even when they were nice,it was very cold , distant and it was like they were talking to strangers. It was politeness. He said that they never behaved that way - cold and distant. He was happy they were not acting bad,but he is worried about where their relationship is going-they used to talk about all kinds of stuff,and now they're thanking him for offering a meal.

He asked them if they'd come to our place on Saturday,but they said they have plans already. So he offered Monday but they said they have to get ready for parties for Newyears eve. So it was decided that they come again tomorrow.

He's planinng to ask them what would they like for Christmas and Holidays as gifts,and I hope it's all ok.

It was ok to me,but BF is concerned about how distant and cold they were.

I'm just very grateful and happy that december82 gave me the idea to talk to BM.
