2 days ago I found out that my boyfriend from last month was cheating on me and how he’s with the girl he cheated on me with. Well, me and him have a mutual friend who set us up, and ever since all this went down she’s avoided me and completely doesn’t acknowledge my existence. And to top it all off me and him are both in her wedding. This whole situation is stupid but i don’t know what to do. Besides I’ve never been cheated on before, so I don’t know what to do or how to feel
