I have been dating my boyfriend for 3 years now and also have been in his daughter's life for that long. Whenever I talk about his daughter, I call her MY daughter. Her mama is not really in her life at this current time and hasn't been for a very long time. 

I love my sweet baby like I would love my own kid. She is mine. Not legally, no but she is mine. I've been helping raise her since she was 2 and today she is 5. Shes so beautiful.. with eyelashes as long and pretty, blonde curly hair. She has an amazing personality. Shes a little.. well extremely wild but SO smart. Too smart, it's kinda scary. Me and her have actually had a great relationship. 

Until maybe like a couple months ago. My boyfriend seems to act a little different/crazy around his daughter like hes trying to entertain HER and not acting like an adult at all. He has been doing this for probably about 2 years. In the beginning of our relationship he was respectful and treated his daughter as his CHILD not his FRIEND. I get that you have to be playful and silly with your child once in a while. But I feel like it is too extreme. And very disrespectful towards me.

It's kinda confusing the way I explain it. Here's some examples: 

Around his daughter, if I want to tell my boyfriend about my day or something that happened, he acts stupid and interrupts me with a silly noise or yells and screams in the middle of my sentences to the point where I dont even want to say what I was going to say. 

Also, when my boyfriend and his daughter are getting too rough (it's ridiculous how wild they get sometimes) I will tell them to calm down or like chill the heck out. And my boyfriend mimicks me. 

The other day, I was sitting on the couch, and this happens a lot. Where my boyfriend and his daughter will whisper about me. Saying childish things like I'm a 'boobie head' or a 'weirdo' or whatever. Well my boyfriend was whispering to his daughter while she was eating. She turns over to me and said laughing, "He told me to slap my food in your face.." and I'm like really?! What if she had done what he had told her to do even if it was a joke? (I would've walked out that frikkan door..)

There's so much more to it than this but it seems like when I'm around both of them this goes on the WHOLE time we're together and yes we have her full time. And when he does these things, it's in front of her, and lately shes been very ugh disrespectful to me. ESPECIALLY in front of her dad.

This is causing me to become very defensive and my relationship with each of them has been strained and I dont know if I can deal with it. Like, why can't we just hang out as a family innocently instead of picking on Jenny and making her look like a fool? 

I've tried to talk to my boyfriend about it because it really bothers me. And every time he says hes not going to change himself to make me happy. I'm not asking you to change YOU. I'm asking you to simply stop disrespecting me in front of your daughter! It's one simple thing I ask him to stop.. i just dont understand why he can't do that for me. I defend him every time she bad mouths him or hits him. Most of the time (not all the time) he'll sit there and watch her disrespect me or defend her when I try to.punish her RIGHT in front of her. 

Its killing me. It hurts. 

So what I want to know is am I being too picky, too jealous, or being stupid for the way that I feel about this situation? I know hes joking but in my eyes its disrespectful. 

I love both of them and I've invested A LOT into this relationship and that little girl means everything to me.. but our relationship hasn't been that great since her dad started acting like this. It's not her fault though. It's his. I just want to find some common ground where I dont feel like I'm being attacked or feel defensive against them two. It sucks. 

But I just wanna know is it right for me to feel this way?
