5 months pregnant and want to be single ?

Ladies I think it’s got to the point that I’m now feeling depressed ! Im 5 months pregnant after two miscarriages so you would think I would be super happy right now and don’t get me wrong I’m super happy about my baby,but now my relationship might be dying ! I’ve been engaged a little over a year and my fiancé said he was going to do all these things for me and did some to get me,but he fell off and has gotten so damn comfortable with just working and coming home and never nothing ! He thinks he’s being a great man to me because he works and comes home and is faithful ... ummm I’m sorry a relationship takes work and I want to do more than be in the house every weekend. It wasn’t until these last 6 months that I realized I don’t like his family for good reason,he’s not good with money,he’s not a planner etc. I really think I want to just co parent and live by myself and get back to what I like and need.
