<human>: I just wanted to say thanks first for everyone helping me. I really appreciate it. Previously on [Reddit] ... 
Slagface isn't invited. After a conversation that lasted an hour, he finally saw it from my perspective. He was upset cause I wasn't seeing it from "his point of view." So I asked him if he really wanted her to come, she could but I'd be seriously stressed out about it. I also told him if Slagface was invited, that prior to inviting her he'd have to have a 'serious' talk about how she treats me. 
He again, got a bit upset, because he's tried talking to her about her ~~bitch ass~~ bad attitude towards me(I already knew this.) I pointed out that she didn't even invite me to her wedding, even after I helped plan/decorate for it; I also pointed out that her inviting just him, rather than the both of us to events(despite us being together for a fairly long time) is no way supportive of our relationship and how we should avoided having people like that at our wedding. 
So, after a while, he understood. He's kinda mad that she has to have such a rude attitude towards me; but he apologized and all is good.

Give me the gist of the text in a nutshell
