A lot of good advice here, and it really makes me sad to read your post. I saw a red flag in your post, and I think part of him is still confused about his emotions over his ex, and he is so comfortable with things being stalled. He wants a relationship, but doesn't. If that makes sense?? He likes the idea of you, and him together, but there is no 'zing' no sense of, 'I don't know what I would do if I lost you.' type zing.
Good luck on getting to the point of taking a break. I think that could be best so that he can spend a while thinking about the relationship, and his feelings. If he loves you and wants you to be a permanent part of his life, then he will chase after you and declare his feelings. If not, there are other men out there who are ready for a good, loving relationship.
