What is a deal breaker

So whenever I ask my boyfriend and the father of my unborn baby what he’s doing or where he is or who he’s going to hang out with he doesn’t want to tell me.

No I do not think he’s cheating but he doesn’t want me in his business ever weather it comes to

Family

Money

Bills

His friends

His privacy

I just feel like it’s not a relationship we have a baby on the way and a home but he doesn’t want to communicate or let me know his business and it makes me feel like I don’t matter and it honestly hurts my feelings
