Father of My Child is an Alcoholic Getting Help

I just gave birth to my 4 month old son in August and it has been a week since my ex fiance whom I was with for almost 5 years came to me saying we can't be together right now because he broke down and realized he has a serious problem and is now getting help from AA. He said we needed to break up because they recommended he not be in any serious relationship while recovering and he says it will be too much being together and taking care of our son. one of many of the things that factors into his drinking he says is that when I use to get really sick-I was diagnosed with toxic stress disorder two years into our relationship which caused me to vomit uncontrollably when I was really stressed or anxious until I was taken to the hospital. He said one of the factors of his drinking was when he found out we couldn't fight like that anymore he started bottling things up and drinking instead of talking to me about what was bothering him. He says that there is still a chance of us being together as a family after he recovers but he doesn't want to get my hopes up because he has no idea how long it will take or if we can be together again.

I know that God has a plan and that if it's meant to be then we'll end up together. But it has only been a week you guys and I feel like I can't breathe. all I've ever wanted was for me him and our son to be a family together and I'm trying to take it one day at a time and find a way to keep it together. To me it feels like we're just taking a break until he is better again but to him It's like we're broken up. I don't know how to deal with this.

I'm so Happy that he's finally getting help he needs and he's still here for me to text and call if I need or want to. But it has only been a week and I'm trying to figure out how to hold it together. all I want is to be with him and for me him and our son to be a family. I never thought that we wouldn't be together for him to get better or that it would affect me like this.
