<human>: Me and my group of friends since middle school *we are all 20 now so about 8ish years* decided to get together to play games and hang out in general. A little backstory about his girlfriend, Ashley and me have never gotten along. To this day I cant think of a time when we weren't at each others throats. *She once sacrificed me to Satan but that's another story*

Since me and Ashley have had past history we asked if it was ok for me to be there so we didn't have any conflict. He said he had talked to her and that she had no problem with me being there as long as I was gone before she came home, so no big deal, the plans were made.

So we all show up, the group is about 8 strong and we are all having a good time playing games and hanging out. After a few hours there is an unexpected knock at the door and behold it is Ashley, I duck into a corner with a few friends and get out of her way since she's not supposed to be there I expect as long I we don't cross paths all should be good.

At that point Ashley pulls her boyfriend into the bedroom and they have a short talk before he comes out and tell me I have to leave, I thought this was just because Ashley was going to be there for a bit so I told them I'd run and get some more snacks and he can text me when to come back. He tells me not to come back....

I was kinda shocked although not surprised, I walked out and as I do he tells everyone he would like them to stay and keep partying. Lucky my friends had my back and everyone left with me.

The next day he asks her to marry him, they are getting married in a month before he heads off to the military.

Summarize the given text in a few sentences.
<bot>: My friend invited everyone over for a party, when his girlfriend makes an unexpected visit during her lunch break and makes him kick me out. I feel betrayed and wondering what I need to say/do to save this friendship.
