Fuck buddy

So this guy is 4 years older than me, had a girlfriend and recently had a baby to her. About a month later he started chatting me up and yeah things got to where they are now as fuck buddies, he told me 4 weeks ago that he is getting back with his ex and completely dropped me on everything. He's the most perfect guy I've met like holy damn, he text me lastnight "Hey how you been?" One message back and he is already asking to meet up again, I know he's a manwhore and is probably still seeing his ex but I'm infactuated with him and would sooo easily say yes. I don't know what to do!! 💔
