how do you all get through it?

My fiancé just told me he doesn't want to be with me. We've been together for 5 years engaged for 2. We have a little girl together. We've been arguing for over a month. But we stopped and agreed to just get over the stupid things we were arguing about. He went out of state to work and then 3 days later messaged me that it wasn't going to work out. I have never been in this situation. I am trying to be strong and not break down. But I feel so stupid and hopeless because I was really trying to fix things and then he just messaged me saying it wasn't going to work. Now I am so worried that he will try and have custody of our daughter or take her. She's only 4 months. I'm a good mom I do everything for her literally even when he was here I did everything. He's never bathed her, washed her bottles he's only changed her diaper like 2 times. He doesn't know how to calm her down when she's crying he's never woken up at night when she was up it's always been me. I'm just scared of what's going to happen to us. I don't even know how to do this alone. I didn't plan on doing this alone but I'm trying because of my baby but I just feel so broken because this was a surprise
