Breakup💔

So I just broke up with my boyfriend of 2 months today. It felt a lot longer because we were talking for a while before. I broke up with him because he didn’t trust me and got jealous if I posted a video of a male friend on sc. anyway I’m going out drinking Friday and I guess I just don’t know how to be I mean do I just forget about him and have a good time. But what if there’s some I like there so I not do anything or what I’m so confused I need some advice
