He's still sleeping with his baby mother. Shouldn't I be mad?

A year ago, I found out my boyfriend was cheating and had 2 women pregnant by him at the same time. I didn't believe any of the women so I stayed with him. He blocked one of them because she was calling too much. The other woman wasn't. But anyways , a year later, the woman contacts him again asking could he see their child. I guess he's been giving her money for the kid that he claimed "isn't his child". I was so upset. Because why lie? He said the women were both lying on him. She even wrote a status saying he's been picking her and her kids up to go to his house. He never broke his neck for me. I have to do everything on my own. So I wrote a status saying that basically I was still sleeping with him too. I guess he told her he wasn't talking to me anymore and she believes it. Smh. Shouldn't I be mad at him? He said he hasn't spoken with her in a year. The other baby mother is around but I don't hear of her that much.

We've been together for 6 years. On and off. I was dating other guys because HE cheated on me first. But it wasn't serious since I was cooking and helping him with his bills every month. I even bought him a TV to watch. When I'm down bad, he isn't anywhere around. He blocks me like I'm a NOBODY. Smh
