How your husband support you during your first time pregnancy

I am week 12 pregnant and first time pregnant. The thing is my partner and i are not married yet so after finding out I am pregnant we decide to get married. Our families and friends also didn't know I am pregnant as we decide to wait for the NIPT test to be out before announcing. But I feel that although marriage is in plan but throughout these few weeks, I didn't get any support from my partner. We decided to keep the baby as after our discussion we decide to start a family and move on to the next phase of life. We are in our forties. But as weeks passed since knowing I am pregnant I feel I am not getting any support from my partner, we lived separately still. He is just not proactive and alot of things like marriage stuff, I am the one finding and I just feel jaded and no motivation anymore to do anything about it. I feel abit regretful in keeping the baby as I have no family, friends to discuss my situation and my partner is just non-chalant about alot things. His talks are louder than his actions I feel. He is still living his single life. I have no confident in him being a husband and father now. I express my concerns to him before but after awhile back to square one. I feel so loss now as I don't know what to do now with a baby in me. Anyone has similar situation as me?
