8 mo preggo w/ex's baby, has he had a change in heart (No lectures please)?

For starters I'm a little confused too :) I think that he wants to try and be a father and part of your family but he is unsure of his relationship with you. Perhaps accepting his doubt and coming to terms with it is a solution. Don't demand black & white answers. He seems to be a very down to earth and pragmatic person. If he is willing to try and you are too, then go for it. In the end it's pure honesty because no one knows how relationships end up or evolve. So you have to move forward even though it is uncertain. Be appreciative of his efforts and involvement. He seems ready to be a good father, but if it is a lover you are looking for, perhaps you need to look somewhere else or perhaps in time your love for each other will grow. In any case, lots of communication and exchanging expectations is certainly a good thing. Hope this is somewhat helpful, it is a tough situation. Wish you all the best xoxo
