When I first read your post, I thought what a sad and hard lesson to learn. Unfortunately, we have all have had to learn a painful lesson or two. I think the best thing to do would be to learn from your mistakes and try to treat the next person you are with (BF) with respect and honesty. You can make up for the past by living a honest life as best as you know how from now and in the future.
Personally, I would never be the type to call up an ex (even ex-husband) if he were in a committed relationship. It would just be causing to much drama and heartache. I am so sick of drama believe it or not.
Perhaps in the future you both may be single and meet up again one day. I am grasping for straws here I know, but you never know.
