Ever since a toxic relationship with an ex, I've struggled with dating. Our relationship wrecked my self-esteem, and confidence in the dating process. It's been almost two years since our breakup, and I haven't even kissed a girl. I've gone out with a couple that I really liked, but got rejected in the end. I think because of the exact issue I described in the title.

I actually feel attractive nowadays. I walk with my shoulders back, eyes up. I've noticed girls looking my way, especally as I've gone to the gym more and more and dressed better. But, when I see an attractive girl, and especially when I'm on a date with one (hasn't happened in a while lol), all I think about is how I can fuck up. I get nervous, my self-esteem drops, and my brain fogs up. My closest friend is kind of a dumbass, who pressured me forever and rubbed it in my face when I was "failing" and he was "winning." Trying to distance myself from him now, but he definitely had an effect on me.

I've literally had pretty girls tell me recently they want to date or hookup, but I still screw it up somehow lol.

What do I do to alleviate this? How do I start feeling more competent and confident around women? How do I rebuild my self-esteem in this area?
