I need some prayers please

I haven’t been feeling myself lately. I’m going through so much stuff. I’m 3 months pregnant and have a toddler also. Their dad proposed to me when he came back from Iraq (we have been together for 8 years)and it was one of the happiest day of my life. I love him very much with all of my heart. We tried for this baby as soon as he got back home. Well now things are all turned. He left me and said that he’s not ready that he thought he was but isn’t. He assures he loves me but I just don’t get it. How can he say he loves me but leaves me? We randomly talk over text but whenever I try t bring something up about it he shuts it off and says he can’t talk about it that he has a lot of stress from work already so I just end up not saying anything anymore. I’m just bottling everything up. And I feel alone.... it’s hard dealing with pregnancy and a toddler already...
