Urrrgghhhh he comes back into my life and I fall back in love with him! what do i do?!?

I know what you mean. the same thing happened to me over and over again for about 3 years with the same guy. i finally got over him thanks to my mates, whenever i saw him or felt like i liked him again me and the girls would go out and just talked. once we worked out why he was my EX i started to get over him again and now i don't even give him a second thought. Hope this helps :)
