Facebook and behind my back she tried to get back with him only a few months into our relationship. He told her no and cut all contact with her for months.
Then at the start of summer she moved back and the first day of summer break he stayed the night with her. I told him I thought I was pregnant. And he told me he had had sex with her and she was pregnant too. I was heartbroken especially after he told me he wouldn't leave a girl pregnant alone, yet left me. He dated her for about a month but kept calling her by my name and things quickly went downhill. She moved away and school resumed, and for the past four months he has been desperate to get me back.
He cut all contact with her. Later I found out he lied about having sex with her. That I was the only girl he's ever slept with. But after the lies and cheating I feel like I'm second for him. Even though he chose me, apologized, and has been open and honest with everything since, including telling her he loved me and didn't want or need her I still feel unimportant to him. How do I get past this and move on with our relationship? (The cheating also occurred when he was high after a boy called him saying I cheated on him with another guy and texted him a Photoshopped pic of me kissing another guy.)
