Most Helpful Guy
Seriously? He wanted the chance to be with other girls and you were gracious enough to give him that chance? Do you have any respect for yourself?
I don't mean to be harsh, but you're not being fair to yourself. You invested two years of your life to a man who you will remember the rest of your life since he was your first. He decides to end it with "I wonder what its like to be with other girls" and you want him back?
I'll begin by saying that exes should not be friends. What reason should they be? Think about it...who wants to sit and idle by and watch their ex get a new significant other, causing them to wonder why this new person is good enough but they aren't? Being friends after dating is insulting...its saying that you're good enough to be friends, but not good enough to be seen in the romantic light without giving them a reason.
In your case, you allowed him to have his cake and eat it too by continuing your sexual relationship after your exclusive one ended. He was clearly taking advantage of you during this time, and when you think back at the times when he was unavailable, odds are those are the nights he was with someone else.
Here you are, 8 months later, having no idea how many girls this guy hooked up with, after using you for sex, and pretty much teasing you to hang out and you're still stuck on such an awful person.
I really think you should move on to a guy who loves you and you only, and doesn't wonder what it would be like to be with another woman. I would advise you to leave this guy alone and avoid him. Don't text him, don't call him, no talking, etc. He's not looking for a relationship with you. At best, he wants a hookup (which is unhealthy for you)0
