Womens advice, what should I do with my ex?

I know its hard but whats meant to be will be.. all I can say is that I left my boyfriend and he was crushed.. I still loved him but I needed to get away.. as soon as I found out there was another girl in the picture I realized that I would never be able to handle not having him.. we are still together to this day and very happy.. Im not saying that you should go find another girl but trust me if she wants you she wont let anyone else have you.. if you know what I mean.
