<human>: Give me a shortened version of the text

Me and my gf of 1 year got into a fight about her past and I said some very hurtful things to her and it made her feel like a piece of shit. Basically i am very inexperienced and she is pretty experienced (sexually) and I kind of made her feel like crap for giving herself away to other people and not saving it for me. I am not perfect I slipped up. I knew what I was saying wasn't nice but I didn't know to what extent it affected her, and it was very very bad because we already had arguments like this. I am not a good boyfriend because what kind of boyfriend makes their one love feel bad and be reminded of there past?

 I love her with all my heart, and the shitty thing is that she's been nothing but a sweet kind and caring girlfriend whom I love so much. What can I say or do to her to show her how sorry I am?
