My BIL(22) is dating a girl(20). They “talked” his junior year of highschool before he dated his long term ex gf until just this past February. This new gf, we will call her Annie, has a 1 yr old child(m). Annie’s baby daddy is supposedly only in the picture now because of my BIL dating her. Annie gives me weird, controlling vibes. They have been dating for less than 2 weeks, he’s moved into her dead grandparents’s home with her, claims the child is his to strangers, leaves my MIL(who was newly widowed in Jan) home alone during terrible storms including a recent tornado less than a mile from her home. Annie put a car seat in my BIL’s truck with less than a week of seeing each other. My SIL & I have birthdays one day apart. We went to dinner for our birthdays at a very fancy restaurant, got baby sitters, etc & my BIL told us that he would not come unless Annie was invited. This is at day 10 of dating. We were all dumbfounded, as this is the first celebration since my FIL’s passing. What makes it worse?? When we spoke to Annie at dinner, she barely spoke. Wouldn’t respond when we asked her things. Ignored us. Refused the offer to try different foods & drinks we all had. Was whispering to my BIL the entire time & not talking to any of us. My BIL claims they hadn’t had intercourse yet, but we don’t believe him(nothing wrong if they have they are grown adults). She is starting to get controlling & even more weird. My husband(30) runs his deceased father’s business with my BIL. An emergency call came in after 10 pm & Annie told my BIL she was going & then sat in the vehicle for over 4.5 hrs in the parking lot as she was not allowed in. From information my SIL & I have gathered, she seems to never have her child either. Always someone else watching him. Every day, we find new things we are all concerned & weirded out by regarding this “relationship.” Let alone Annie telling my BIL that she would “stalk his & ex gf’s instagrams to know when they broke up.”

AITAH for digging for info & already disliking her? They’ve been dating for only 16 days as of this post.
