I was with my boyfriend for a year and we lived together for about 8 months, he was faithful and everything was perfect, we started to argue quite a bit during the end of our relationship and we split up he told me he didn't feel the same because of the arguments but suddenly one day said he regretted dumping me and we got back together. This happened again over a month ago but this time its for good, he has never really had many girls interested in him but this time his friend has found him a girl who really likes him and he's meeting up with her constantly. We slept together again the other week and he said he loved me and wanted me back (he was slightly drunk but so was I) then last weekend he told me he wanted to try and make another go of things, but now has told me he didn't mean it. He says he doesn't want to be with me because it doesn't work because of the arguments, yet he still texts me and speaks to me and says deep down he still loves me. I don't want to lose him to this girl, what do I do? I am not ready to let him go as I know him extremely well and know that if he didn't have any feelings for me he wouldn't speak to me at all (what he did to his last ex girlfriend) what shall I do!

Tell him to quit contacting you until he makes up his mind who he wants to be with because you don't want to deal with your feelings being treated like a yo-yo.
IF you do get back together you need to learn how to talk things out in a normal constructive way rather than destructive arguments. If he wants back with you it would probably be a good idea to tell him only if the two of you go to counseling because you do not want the arguments.

Drop the guy and meet new people. I know its hard but perhaps the best thing to do.
And DO KNOW this is just an opinion and is likley VERY difficult to do when your heart is in the way.

Stop letting him contact you, drunk or sober. His words and actions, don't match, do they? As he still has a chick on the side. No Contact, just disappear from his life.

Was it really because of the arguments that he's breaking up with you? If so, what were the arguments about?
