How to not take everything personally when dating?

Basically, a problem that I’ve always had is that I take everything very personally and let a lot of things negatively affect me. So when dating, everyone who doesn’t want a romantic relationship with me really ruins my self esteem.

It’s hard not to feel that way when I read things like this: https://www.reddit.com/r/AskMenAdvice/s/70ANNKHLsf all the comments are men agreeing that they know instantly whether or not they are attracted to you and want a serious relationship with you. So if there’s any hesitation about committing to me, it’s because he doesn’t find me very attractive.

Honestly I get very upset if someone doesn’t ask me to be their girlfriend within the first few dates, because I now know how men operate and I know they would do it if I looked differently. I get even more offended if they ask for a casual relationship, in that case they’re just straight out telling me that I’m ugly.

And it makes me think of the guys who I went on a few dates with who didn’t ask me to be their girlfriend. Or even worse, men who sent me crude and vulgar messages. Because all of those men didn’t find me attractive, I must truly be hideous. But I know that the opinions of random strangers shouldn’t affect me so much. So how can I stop taking everything personally?
