He doesn't realize how much he hurts me

And when i thought i couldn't be happier, i'm in tears all over again. He makes digs at things i say for pointless reasons. I was out with all the girls last night, but then we went to kirkton to see Ben, Gary, Alfie etc. Then Ally was so off with me in his texts and i phoned him to try and talk it over and he just didn't want to talk, saying nothing was wrong. Then he was apologizing be so nice and saying it was just all jealousy and that he doesn't like me hanging about with other guys but that he was just being a dick. I phoned him to tell him it was ok and that he could trust me. He went mental 'Get intae whoever you want! I don't even care! Don't phone me!' Bringing up kissing my friends again and again. But that's my fault, i know i should never have done it but i really cant take it back and you know half the time he says he'll get over it. I know its not that easy, and i don't expect him to trust me straight away but im trying to show him he can trust me. I was in tears and he was just shouting he doesn't care. And then changing his mind, that he's the one being a wank and that he loves me. And i take all that, i let him win the argument, because loosing the arguments better than loosing him. He hurts me more than he even knows, i know he doesn't mean it. He gets angry and he has reason not to trust me. But its just that switch in his feelings so fast i don't even know where i am half the time. I don't think he near realizes how upset i am about all of this. But you know what, i'll take all the shit he gives me because i love him.
