Breakup or no

So hey guys lemme get right to it I have a baby a beautiful baby girl and my baby daddy (current boyfriend ... ex atm but you get it). I found out he had nude pics of a girl we BOTH know in his phone saved on Snapchat. I’m obviously like over him done w it bc the past few years all I’ve done is support him ive paid for everything I’ve taken care of him and my daughter basically all on my own. Actually, completely on my own lol. I’m just like wow right?? I’m not being ridiculous? I don’t want to be together bc he shows me no affection, no appreciation, he’s say sits around and does nothing and I do everything bc I love him but this is stupid I know I sound stupid but everyone says I should try to work it out but like that’s so stupid!!! I have done nothing but try my best to keep this man happy... why should I stay with him after ALLLLLL of this? What do you guys think?
