Okay everyone, I've got a new and mystifying problem here.....

SD, 24, texted me last weekend (she NEVER texts me!) saying "I miss you guys! are you going to be in town next weekend? I want to see yall!" WTF?! This is the same SD that claims I've come btwn her and DH, screamed at me, caused all kinds of drama at family gatherings, etc. I texted her back, stated that we would probably be in town, and that I'd tell her dad so that we could (excuse me, HE could make plans with her..). Okay, so this weekend, yesterday to be exact, DH called her 4 times trying to get hold of her (she never answered, never returned his calls) so we could have dinner with her (I decided to try to be forgiving and make dinner for everyone). DH started to panic, thinking something was wrong, car wreck or something; I picked up his phone and texted her-"Okay, your dad is getting upset. Are you okay?" This was her response-"I'm at a movie with someone-I'll call later". So much for "missing her dad"! Anyway, DH calls her this morning, gets hold of her (WOW!!) and asks her if she wants to go to church with us and my MIL. She says yes, I'll meet you there. Well, guess what? She's a no show! No suprise-DH was very angry, and MIL was disapointed, too. Both DH and I left our phones in the truck, so when we got out of church, I checked my phone, and this was the text msg...."Please tell my dad I'm soooo sorry! I had plans out of town with friends....can't be there." Now, why is she texting me, the dreaded SM, she won't call DH, won't return his calls, (she will if she needs money!) Why is she doing this?!! I do not want to be in the middle! The good thing out of all this is DH is finally seeing that she is a spoiled little witch-I just hate that he's upset about it! What do think?
