Your boyfriend doesn’t want to be with you, and he is conflicted at best about the baby, and doesn’t want you to have it, at worst. Don’t blame him. This was an unexpected pregnancy and it’s normal for him to be conflicted and/or not to want the baby and/or definitely want the baby. His feelings are going to be all over the map. However, [i]your[/i] feelings for the baby are separate from his.
It doesn’t sound like he’s coming back to you in any permanent way. He gave it a try for the sake of the pregnancy when he found out after your break up that you were having a baby. But it didn’t work. Don’t count on him coming back in any permanent way for you. You need to move on and prepare to become a single mother.
Try and keep your relationship with him civil and friendly since you will be co-parenting a child together. I know this is a tall order, but try.
