<human>: Can you provide a brief rundown of the text in within 3 sentences?

The majority of my cousins in my generation are older than 40 due to a large gap in births, and all of them are either married now or have been married in the past. After I sent out save the dates, my cousin, Bob, messaged my mother on Facebook about bringing his daughters. The invitation was addressed ONLY to him and our website (listed on the save the date) states it is an adult only affair. My mother politely said "I'm sorry but we cannot accommodate children" and he said "well why can't I bring them to the church?" and my mother replied that no other children will be invited because it is an adult only affair. Well thankfully he got over it because his sister's are going and won't be bringing their kids. But then a month ago he tells his sister he is bringing his girlfriend of 3 weeks so his mother can meet her at the wedding! He doesn't get a guest because he is a single guy who can't hold down a relationship for more than a few months. I love that my awesome cousin let me and my mother know and she (the sister) told Bob that the new gf won't be invited because he doesn't get a plus one. 

Today I was at my mother's house and she had news from MJ, who is my super super awesome cousin (she is my day of coordinator because she doesn't take people's crap). MJ was talking to Bob and Bob informed her that he probably won't come to the wedding anymore because his girlfriend isn't invited and he was offended I didn't invite our other cousins from Connecticut (FYI they don't give a damn). I don't know those cousins very well but I did invite the "heads" of the family because, well, they are family, and I have seen them at most family parties. Plus, if we invited everyone that would be **12** seats at the reception I would have to give up for people I barely know instead of having friends or family who I do know there! 

I told my mom if he says anything I'll just tell him to cough up the money for the 12 cousins haha! Kidding of course. I'll be my delightful self and say 'no' then curse him out under my breath. :-D
<bot>: Pain in the butt cousin wanted me to invite his kids, then his gf, then 12 other cousins. Probably won't come to the wedding anymore. Oh well!
