What shall i do? Another boy thread!

Hi, Basically to cut a long story short i was with this boy on and off for about 5 months. However he was still getting over his ex which is the reason why we were so on and off. We both liked each other loads howver he decided that he needed to be single for a bit. Yet be both kept getting togeather and sleeping togeather (mistake i no). But whenever we went out clubbing etc he would always comment to his mates how nice other gals were etc. Then the other day he started dancing with this girl so i kissed this boy. Bearing in mind that he has done this to me many times! He then blanked me and since this occured (1 week ago) we have seen each other out twice but just said hi. He is now texting this other girl who he 'likes'. I just cannot get him out of my mind and dont no whether to text him or just leave things. He has told people that he doesnt like me any more but i no that he does by the way he looks/ watches me (well i can just tell). What shall i do? Help!

Thanks for reading this and sorry if its a tad confusing.
