<human>: Can you provide a brief overview of the text?

I had a long term relationship with a guy from when I 17 to 19. Some of the things he said to me still really upset me and I can't forget them. When he broke up with me after one year he said to my face he thought I was unattractive (we got back together after). I also found something he wrote about me saying I was bad in bed and sex with me was boring. 
I feel insecure that he was right because every relationship/ dating I've had since has always ended we me being ditched by the other person. 
I don't know what I can do to forget these comments. Other people have also made comments about my chubby face and small boobs. I feel pretty unattractive.
<bot>: Ex told me I was unattractive and bad in bed. I still feel hurt by what he said and can't shake believing it to be true.
