I sense that you already know what you need to do with regard to this situation. It seems like this guy never could totally commit to you. He was with another woman on and off during the time he was first with you. Then he tells you that she did not give him the love and affection that he needed. RED FLAG! Do you want to be with someone who you know to be also involved with someone else?
Then you made arrangements to meet and he did not follow through. Another RED FLAG! He is otherwise involved. He most likely does have some feelings for you, but he doesn’t seem to have the ability to stay focused on one woman for any length of time.
The age difference could also be a factor. It might not be apparent now, but could be more of a problem in the future. Don’t wait for him or plan to meet with him again. This could only result in more hurt. You need to be with someone who will treat you with the consideration and respect that you deserve. So just go on about your life and you are likely to meet someone where you now live who will be right for you.
Best wishes,
