I moved to a new school this year and ive made friends with a group of girls. We were at a house party the other night and one of the girls had a fight with her boyfriend and went home. Me and him walked to a shop to get some food and he kissed me and told me he liked me. We were really drunk btw. I kissed him back and then stopped and said but you’re with Ellie, and he said I’d rather be with you though, and he kissed me again. I said ok, well you need to break up with her then cause I can’t do this behind her back, he said ok I will. He got out his phone and messaged her saying ‘were finished, I like someone else’. I’ve said to him that I want us to keep it a secret for a while because I don’t think it would be good if she found out yet, and he said ok. So we’re basically pretending we’re not together right now and when she asked him who he liked he said it was someone out of school. 

Anyway AITA for basically telling him to break up with her and now secretly dating him?
