ive been in this position before.. but my ex was just a complete ass hole, he actually went behind my back, not once but TWICE and i didnt know about it til i broke up with him.
I THOUGHT i was in love with him but i was just young and stupid (started going out with him when i was 15.. and i was with him for 1 year and 7 month)
But the thing is, i usually did wanna break up with him when we argued n stuff, i used to think to myself: what the hell would i do without him? i never thought i could live with breaking up with him but then one night he was out drinking.. i was too but we were with our friends in different clubs, i tried ringin him.. kept hangin up.. then this boy (whos now my current boyfriend) started talkin to me.. i sorta knew him as he lives round the corner and went to the same school but in the year above me.. we got talkin etc. he bought me drinks, he was just so sweet (nothing like my ex) then we swapped numbers, the next day something happened then my bf found out i was with another boy... he said he doesnt wanna be with me no more, i actually felt like shit like really bad, ive never been with someone so long and just broke up. but deep down i was actually happy. The next day i was with the new boy and he came to mine.. we were talking from about 6PM til 3AM!! we had so much in common.. my ex rang my mob and was saying sorry, saying how he loves me and didnt mean it etc. Then he realied i was with another boy.. he was upset.. then he was on msn begging me to ring him.. i was like FUCK THAT, now im soo glad and proud of myself that i broke up with him, i know it sounds a lil silly that i was with another boy when i shud of been with my current bf.. but he was an ass, he shudnt of hung up on me! lol that teaches him. and now hes with this ugly girl who has huge thighs and hes gone fat too... must have been comfort eating because he lost me (lol)
anyways so what im tryin to say is... if you really deep down dont love him, you know that hes hurting you then you dont have to cling onto him, if i can do it anybody can. I know it seems hard at first.. thinking how are you gonna cope without this person.. but you feel so much better once you're away from them, they cant hurt you no more... seriously hun he does sound like he doesnt listen (but what guys do right?) hes not gonna change even though he says he will.. but its not gonna stop him doing it again because its very rare that people do change..
i hope you make the right decision for yourself, just think about yourself and what else is out there waiting for you?
