<human>: Could you distill the essence of the text into 1-3 sentences?

I had an argument with my boyfriend of 2 years, a couple of nights ago which resulted in us breaking up. Our relationship has been really rocky this past while and we both seem to be going in different directions. 

Anyways yesterday we were arguing some more and during the argument he called me a 'dyke'. This was directed at my last relationship as I was with a girl for 3 years before I met him.

I was 15 when I met her and she was 18.I was very vulnerable and impressionable and she was just someone who was there for me.
Throughout our relationship I had repeatedly told her I knew myself I wasn't gay. I was attracted to boys. She tried her best to keep me but in the end up the relationship ended badly.

Anyways while I was with her, I thought if I did break up with her I'd never find a boyfriend. I didn't think I was good enough and no man would be attracted to me. So when I started going out with my boyfriend I was over the moon. I told him all this and confided in him a lot.

But yesterday when he called me a dyke it hurt really hard. I thought I could trust him with my past and now he is using it against me. He knows how embarrassed I am about it. 

Maybe I just don't have thick skin. But what does this say about him and the way he see's me?
