I’m 23, and my boyfriend of 3 years has left me.

I (23) met John (23) about 3 years ago in March of 23. We have a 1 year old.
Everything seemed perfect.
John got laid off three months after moving here, so I went to work. I was burnt out after a month because John wasn’t helping. He never helped with the house. I felt alone, I fell into a depression. I didn’t want to do anything. Sometimes he’d help by sweeping the floor or doing some dishes. He would say things like “why are you acting like that?” Or “what? You’re just going to sleep all afternoon?” Two months of this, and his friend, Sarah, comes to visit. She brings her friend, Jane. They were supposed to come for dinner but John told them just come early. I panic. ‘This isn’t the plan. Everything is going to go terrible because they’re early.’
When they got there, I had a breakdown. John called me embarrassing and I was overreacting. I calmed myself down and as I’m walking through the hallway he’s laughing at something Jane had said. I felt a rush of embarrassment and hid again. When they left, we had a bad fight. They came that night, and I was ashamed to have acted that way so I hid. John was disappointed. A month passes, we celebrate our son’s birthday, start trying for another baby.
Sarah and Jane come back. We have dinner at John’s mom’s house. I have work the next day, so I go home around 10pm. 1am comes and John isn’t home. I call. He’s drinking in the pool with Sarah and Jane, and I ask when he’s coming home. He says “I’ll come home whenever I fucking want.” He stayed AWOL for 5 days with the girls and Sarah’s family in a cabin. I’m told he’s at his mom’s and to come talk. I tell him I’d work on myself if he’d just come home. He broke up with me saying he’s unhappy and we argue all the time. I beg him to not do this. Him and his mother say I need therapy and I need to get better so maybe things will fall into place. They try and convince me for three hours saying I’m miserable. I’m not, I just want his help. So, eventually I have to go home with our son alone. A day goes by. He wants to keep our son for the night, so I say yes. I drive over and try to persuade him to come to couples therapy.. he says that “for now” that won’t work. I go to our friend’s, Sydney and Chase. Chase has been friends with John since middleschool. They tell me to stick up for myself, but I give Sydney my phone and said “you do it.” She logs into his Snapchat and sees that he’s been messaging to Jane. He tells Jane that he misses her, they’ve made plans for her to come back down and spend time with him and our son. They fall asleep on the phone and when she felt anxiety, he reassured her that he loves the way her brain works. Sydney lost her mind and messaged John off of my phone. He just tells “me” I’m torturing myself and have no idea what “I’m” talking about. I literally just wanted support. Is it even possible for us to make it through this?

Update: I found out I was pregnant the day I wrote this.
