Am I being over emotional?

My daughters dad and i had a really rough start to our relationship. The pregnancy was a huge surprise. We decided to try and make it work, and so far it’s been great, but I’m always second guessing his love for me and i don’t feel like it should be that way. I’m just not feeling that same energy that I give him and it makes me sad. I’ve talked to him about it and he assured me that he loves me and all that. He’s just either really bad at expressing his feelings or he’s just not into it but feels obligated to stay because of the baby. Which he also said isn’t true. I just feel like everything around me is falling apart all the time even when he says everything is all good. If you read all of this, i appreciate it. I just needed to vent and didn’t know where to turn 😭
