im in trouble and I don't know what 2 do

Obviously you love him way more than he loves you. See, when you really love someone, you are not selfish and therefore want to give your all to that one person. If he’s with someone else, he can’t give his all to you. He’s giving his love to his girlfriend and you’re getting his sloppy-seconds loving. And if he really really really do love you, then its better that he just leave his girlfriend because you can tell him the longer he’s with her the harder her heart will break. Anywho- I think you should leave him alone. Maybe him and his girlfriend are having a hard time being together because you are in the way. If you were out of the picture, he may realize that he dont love you but his girlfriend ONLY. I know this isnt what you wanted to hear, but its better than your feeling growing and growing and then later he decides to end it with you. Or on the bright side, if you leave him alone to be with his girlfriend, he may find that all he can think about is you….and its really YOU that he wants in his life, and this will make it easier for him to break up with his girl. And as far as him being sad for you not talking to him, don’t worry about that- he’ll get over it.
