Please help me.Cynthia.---------------Hello Cynthia,Your case is a simple one. Let him go.From your mail, your ex-boyfriend is still hung on his ex-girlfriend which was why he got backtogether with her right after you broke up with him.As much as you say you love him, it's clear to see that he doesn't feel the same way and it's sad because you said you've built your life around im.What you have to do now is to untangle yourself from the drama associating with your ex brings, learn to be more sociable, go out more often. You are still very young and have your whole life ahead of you, for now you can just go on dates not because you are on the lookout for a potential boyfriend, but just to have fun without any sexual attachment involved.Find other things that make you happy, set achievable goals for yourself.If he’s the one for you, he’ll notice the distance and come back but you don't have to dive backinto that pattern. Let him know that you made achoice to let him go and you intend to keep it that way.I wish you all the best.--
