<human>: Can you condense the text into a few key points?

It's been over ten months since she left me, I tried my best to win her back, last attempt I bought her flowers and tried to meet with her, she simply saw me, ran to her car, and peeled out, then texted me telling me she never wants to see me again. (This was 2 months after the break up, since then I have gone 8 months with No contact whatsoever)

My problem is that every night when I try to go to sleep thoughts of her still replay in my head, I constantly blame myself for maybe being horrible at sex (She said I was great, But IDK if that was true or not), inexperienced at relationships, maybe I was moving our relationship to fast etc...

So here I am every night trying to sleep, blaming myself every night for what could have been.

I have devoted most of my time to work, hitting the gym, and doing Jiu-Jitsu, so I can go most of the day without thinking of her, but how do I deal with it at night, when I can't concentrate on other things?

If you need any other information pertaining to the relationship, myself, or her I will gladly post it, but just help me figure this out.

Can I really trust what her Best Male friend messaged me?
Am I really to blame for all of this?
How do I stop thinking of her at night?
What do I do so I stop comparing her to all other women I meet?

Thank You Reddit
