BD issues -_-

So, I am almost 18 weeks pregnant with my second baby.. BDs first. We were trying to get pregnant, when we were together.. But have sense split. Backstory, we moved out to California together-from Ohio-where the cost of living quadroupled. While we were in Cali, I immediately began work as he (what seemed like..) refused to get a job. I was so confused, as he seemed to have lost all of the motivation, and drive he once had for us to create a new life together across the country. country. We were there for nearly 2 months.. Mind you, we had no family, no friends, or anyone out there to rely on. His lack of effort terrified me, so I told him I wanted to quit trying to get pregnant until he could prove to me he was the man I once was in love with. I began to resent him, as I felt he saw this move as more of an extended vacation where he could live off my dime rather than a family move trying to make things work AS A TEAM. Not to my surprise, we were forced to come back to Ohio as I could not solely support us off just my salary. We then learned that I am pregnant. Since, all we do is fight. I have lost faith in him as a man. I no longer can trust anything that comes out of his mouth.. As he says a lot more than his actions show. I broke things off with him, in hopes that he would find it in him to become again the man I once knew. Since being back in ohio, he has seemed really depressed, fighting for my attention and affection worse than my 6 year old does, it seems we've lost any ability to productively communicate.. And I think it is all sourced from our trip to California. I am terrified to have a child with him as I'm not sure he is responsible enough, driven and motivated enough to keep working to help provide for this child, I fear he is going to be more jealous of the attention the baby needs that I am unable to give to him, I feel like since we no longer are capable of communicating we will never be on the same page again in regards to how we want to raise our son. He believes it's "just pregnancy hormones" that are causing me to argue with him about literally every little thing.. But to me, it's much more. My question is.. Once you feel you've lost all faith in a man, is there any hope to things perhaps turning around? For me to change my mind, and maybe see him again in the light that I once did? (we're both 26, and have known each other since we were 13.. Been together for about a year, before I broke it off with him)

Thanks in advance for any advice you may have!
