Is this wrong? Bf commenting on girl on insta?

So i saw the date i was 8/9 months preg at thr time. And i just gave birth on thr 26th of March

Anywho. She looked like an insta thot. ( he follows alot of insta yhot pages and stays in contact with exs) What tripped me out was the fact she stays near him. I dont mind liking celeb photos. But this girl isnt one and shes near him.

In the pic she was fishing for atten saying she was bored and all that and he commented why you sad ma?

Prior he has told a girl that her hair looks better than mine. With thr bogus excuse of making her feel better abt herself.

I broke up with him so many times but we have a daughternow...

Anyway is this reason to break up?
