Sounds like he never really loved you. Sorry, I know how much that can hurt. When you're actually in love with someone, you zero desire to give anyone else attention other than your partner because you feel fulfilled. It sounds horrible, but you should be glad you two are no longer together. Now you don't have to waste any more time on someone who was not right for you and you can find someone else you will truly love you wholeheartedly.
