Should I be mad at him!?!? Please help.

Today is Father’s Day and I was hoping I would spend some time with my boyfriend since I mean we do have a child together, but he decided to go to a bar that has girls half naked and I think half naked is an understatement. I’m just so heated because I feel like it’s so disrespectful! I had a friend tell me I was over reacting but I really feel that I am not! I feel like just because I’m not beautiful enough he had to go and see it somewhere else? I’m just so mad and I honestly just want to kick him out for disrespecting me this way. I’ve told him in the past that I would be so mad if he went somewhere like that, and he did it anyway. What should I do? Somebody please help me 😞
