Lying boyfriend

Kaitlynn

So I just found out my SO lied to me about where he was last night and I found out through some OTHER GIRLS instagram. Mind you I've had problems with the girl whose insta it was and him before and she and I got into it, I was nice when asking for the truth but honestly I don't know what to do. He told me he was asleep at his friends while he was at a party and I was home sick throwing up. So I need advice and not negativity thanks🙏🏻☺️
