Break up...

So, i have been with this guy for a year and two months. Very much in love with him but after six months we broke up.... and since then we have got back together and broken up... 5 more times! Today was the sixth time. I still cry but it doesnt hurt as much. He treats me like a doormat, i know...

One minute he loves me, the next he doesnt

So i cannot go back this time!

I just need a bit of motivation and advice to grt ove him... anyone?
