I (28f) have been dating my boyfriend (32m) for over a year. He has his ex named Claire (30f). They dated before I came along and dating for 2 years. She constable kept cheating on him with a guy at work and at the bar so he had enough and called it quits. She keeps creating new numbers, social media accounts, etc to contact him. He's constantly blocking her. He wants to go ahead and get this closure thing over with so maybe she will stop. I told him I'm not comfortable with that. We got into a argument and I grabbed his phone. He was already talking to her on Snapchat. Things got more heated. I told him to go be with her and leave me alone because this is just constant drama and I'm not here for it. He grabbed his keys and left and turned off his phone. It's been 3 hours. AITA?
