I’m sorry, but it sounds like your now ex-boyfriend is moving on with his life for better or for worse. You may be right that the two of you would be great together. However, he has made it clear he’s marrying the girlfriend he got pregnant while you two were taking a break, and is going to make a family with her.
As much as you feel that he is making a mistake, it’s his mistake to make. He’s making it clear to you by not talking to you, that he doesn’t want to be involved with you right now. While it’s going to be difficult because you have a past with him that is mostly positive, you need to respect his decision to start a new family with his pregnant fiance.
It’s fine for you to want to accept a stepchild into your life, but for the child’s sake, the best possibility is a married mother and father. For that reason, you have to call up your most mature self, and move on with your own life, without your ex-boyfriend.
