Being Single

So I've been single for about a year now and I thought maybe it's time to get back into dating. Well after almost 2 months I got nothing, idk why but it feels like I'm just not pretty enough or that all guys want is just sex. I happen to meet this great guy, to find out that he was married 😤, and then I met this other that got mad and stopped talking to me because I didn't want to have sex with him on the first date 😒. I feel like giving up and just accepting my faith of probably being single for a long time.
