How do y’all mommas do it 🥺

My husband decided he wasn’t happy and left me at 36 weeks pregnant with our 3rd we have a 10 yr old and a 1yr old. I had my baby alone, I came home and was alone. He helps when he wants to but it’s just me. I’m so tired and I have 8 more weeks of maternity leave left . I know it’ll be hard once I go back to work (military). I’m trying to decide if I should get out. I never thought I would have to worry about any issue like this I didn’t think he would leave. I asked what his reason was and he said he didn’t like that we didn’t have sex ( I was just tired from work and school and normal pregnancy matters) 🙄 and he didn’t want another kid. Any single mamas have any advise!? I’m so confused.

Thank you ladies, I’m waiting tbh a small part of me has hope that he’ll come home, while the other logical part is like f him. My family lives 4 hrs away and we just moved here when I was 36 weeks and that’s when he dropped this bomb on me. I was so hurt. I feel like I’m stuck to do anything at this point because I’m hurt. He’s active duty military as well so it also makes it harder in the long run (different branches).
