Husband moving 6 hours away

Superblessed🐑🐝

So my husband is leaving me and moving 6 hours away. Last Sunday he told me his kids were going to live with his mom who is 6 hours away because we needed to work on our relationship but I wasn't ok with this because his kids should be here with us so that we can all work on this as a family. I told him he should be with his kids so that night he decided he was going to leave and live there as well. The next few days I came to the conclusion that it would be ok for the kids to be gone while we worked on things because I knew with God's help that the kids could come home sooner and we could mend what was broken. I tried to convince my husband that I need him here with me. Im pregnant with his child and we have a 3 year old together but he wasn't willing to stay so we could work on things. On Thursday he told me he was going to stay and that made me feel so good and positive about our marriage but then when I went to work that night he started moving stuff out behind my back. I called him and asked him what he was doing and he told me he's leaving. I came home from work send told him that my heart is telling me to beg him to stay but my head is telling me to say goodbye so I told him goodbye. This isn't the first time that he's told me he's leaving. He wants to work this out 6 hours apart but he hasn't even tried to convince me that we can make this work. He refuses as a husband to help me financially and won't be there for me during this pregnancy. He thinks if we work it out he can just move back with his 3 kids in 6 months. I'll have a new baby in 6 months so I told him I wouldn't need the added stress of 4 people moving back in right after giving birth. He doesn't think there is anything wrong with that.
