Aww, I'm sorry you broke up and are feeling down. Really everyone has had great advice so I will probably sound liek an echo. Ultimately it is up to you and whether or not you are willing and able to take on the consequences of which ever action you choose. I've been on both sides, I've felt like you before and "wondered" about soemone else and I've also turned down an opportunity and wish that I hadn't so it really is your call. I do agree that you probably need some time to yourself to sort your feeling out and weigh the pros and cons before jumping into anything whether its back w/you b/f or w/ this other guy. Good luck and keep us posted!
