Hey, Rose of Cairo, you are very powerful! That is wonderful and inspiring, and I hope you make the most of it.
As far as romance goes, what do you want, really? Do you want to have a fun adventure with this guy, or do you hope that he will be a long-term relationship? If you want to use the Law of Attraction to generate what you want, be clear with yourself about what you want -- otherwise your fuzzy conflicting emotions will keep you in limbo, and you won't be captaining your own ship.
Either way, the big question is: what kind of a romance are you willing to have with a man who has no integrity? This man has no integrity -- he does not do what he says he's going to do when he says he's going to do it. Unfortunately he did not grow integrity during your three year separation, and you will not change that about him. So, what kind of relationship are you willing to create with a man whom you will never be able to trust or rely on to keep his word?
Since you are such a powerful and intentional person, maybe you would like to experiment with him -- this is a really good exercise for yourself and your relationships in general, not just him -- be totally straight with him. Tell him straight out: "You have no integrity; you don't do what you say you're going to do when you say you're going to do it. You have trained me to not believe you or rely on you. That doesn't work for me for a long-term romantic partnership. Even so, I love you exactly as you are, and don't wish to change you. I would like to have (x romance sex -- whatever you decide you want) with you. I'll still be on the lookout for the right guy for me long term, so I won't commit to you, but it might be fun to have (x romance sex) for as long as it lasts. How does that sound to you? What do you want?" And listen to what he has to say.
You never know; you might have more power to generate exactly what you want than you're even aware of.
