Men & women, I need your help...What's my problem?

Maybe you're looking in the wrong places, don't want to date a larger woman? Try talking to some people in the gym, join a fitness class. Find someone who has similar interests as you. As for being let down, it could come down to sheer bad luck or perhaps you do something wrong each time, Seeing as the want to be 'buddies' ask one of them perhaps? in a non-awkward way. After a divorce it will take a while to get back into the dating scene, and times may have changed since you first started dating? Good luck anyway!
