issues with boyfriend

well i seem to never do nething right. every time i do something jamie always has to say something and make it into something i never thought about. like to night we were sopposed to take a shower together and its 100am and trigun comes on at 130 so i was doing something i got the towels striaght put them in the bathroom and then this song comes on lips of an angel which reminds him of his ex that i cant stand but im gonna put up with her cuz there are freinds. but then 115 comes around and jamies like well i guess we aint takin a shower tonight. so i decieded to take a shower by myself and i got out and then jamie was like we i guess u didnt want to take a shower with me thats y u waited so long ot take it u thought since trigun came on at 130 that u would wait and then take one with out me cuz u knew i wouldnt come in. but thats not it at all i didnt even think about it. and hes waslike u worthless peice of crap. and hes always talkin bout his ex weather hes joking or not. lik ei love her more then u and im with cheri. he joking cuz it pisses me off but deep down i feel like its the truth. they have been talkin and stuff. but cheris the type who… i dunno i hate her. i have never had a realtionship woth jamie where he was all mine there was always another girl and i try talkin tohim but he acts like he doesnt care. i write emails i try to talk to him bout ho wi feel but he jsut thinks iot stupid, and ima try and trust him with cheri but hopefully he cares enough now not to do nething with her i just wnat the reasurince from him that he doenst want to be with her but when i ask i get i dunn o and i gott he out of shower
