Should I let it go?

I've never done a post. I'm looking for constructive responses. I recently gave birth and the father isn't in his life.

I'm not sure what if anything should I do. The guy seems to say one thing and does another. He initially said he didn't want another child when finding out about the pregnancy, yet I later find out he is in a new relationship with a woman that has children.

I asked prior to having my child would he want to know when the baby was born and he said "I'm not opposed". Since this was not a direct yes or no it left me confused.

I send photos after my son's birth and let's him know that he was born and the date. He doesn't respond.

Finally I ask does he want to meet him. He reaches out once free and the only thing he says is he's heavy after picking up my son.

I'm not sure if I'm supposed to let it go or should I continue trying to see if he wants to be in my Sonshine's life.
