“New” single mom-He left us

First and foremost let me start off by saying he’s a good guy and a good dad. We’ve never needed anything. He’s been my boyfriend for almost 4 years. If I’m all over the place my bad. I just need to vent, i have no one to talk to, to text, to call. I’m embarrassed. I don’t know how to do this. I mean I kinda know because I’ve been doing it, so to say already, but now it’s really real. He just moved out today so I know it’s really over. I’m a single mom 😔He works 12-15 hour days sometimes (business owner), he would come home at around 6 leave around 7 to the gym and wouldn’t be home for the day until 9/10. I know he was faithful the entire time there’s no doubt about that but he said he needed to go to the gym everyday because that’s his stress relief. Our fights were always just about him not being home enough to be with us, he always thought it was work, I never had a problem with that because I understood but I never understood why he needed to be in the gym everyday for 3-4 hours a day. I would get mad and keep it to myself because I don’t have the heart to leave my child for 2-3 hours a day 2 times a week to do my own thing. I would always cut it short and race him to be with my baby. We were more like roommates for about 5 months because he stopped sleeping with the baby and I so he could get a good nights sleep. Again, I guess I understood because I’m a stay at home mom but I would always ask him to come to our bed on days he didn’t work but never did. I never did my end on fulfilling his needs all the time (a couple of reasons behind that but i should’ve done it). I would try but no joke 2 out of 3 times baby would wake up crying his eyes out so I would go tend to the baby. I’ve been trying to fight depression for a couple of months now, Ive felt alone for months I’ve felt sad for a long time already. He left us. It’s so hard not cry, it’s so hard to smile at my infant child. I don’t feel like I deserve my baby because I let my baby down. I don’t know how to do this. I’m really alone now. As he was packing his things I don’t think I made it any better. I was being petty I would just say “you’re really leaving us?”I put our letters from years ago in the luggage, our pictures. I took off my jewelry he gave me and threw it at him and I got my phone and transferred every penny I had in my personal account $1,723 to him because he was talking about how I have such a good life not many women have that if I wanted a $1800 purse I just went out to get it, I got the purse after literally looking at it and wanting it and window shopping for this purse for over a year! Over a year!!!! He told me months ago to get it but never did. We went to the mall one day and he’s like this is your chance to get it and I felt bad so I didn’t. The entire night still home I kept thinking about the purse and he kept pushing me to get it and the next day the same he kept saying go get the purse I know you want it you deserve it so at 6pm the following day I caved and went to get that purse comment got me so mad! I wanted him to stay so I was being petty so he can change his mind and stay but he didn’t. I regret everything I said and did. I swear im never mean but i did say things I regret because i can’t believe he was leaving us. I want him back I want my family together. How do I get my family back? Help!

He said he couldn’t keep coming to a house he doesn’t feel loved in. A house where we sleep in different beds. He was tired of being sad, depressed, and lonely. Dating for almost 4 years. We have a 9 month old baby.
