Is it normal to completely give up on dating?

I'm 21 years old and have been single for a few years now. I had a girlfriend but I found out she was only dating me because she happened to read one of my bank statements from in the past. I've never been good with women, I've always been hounded by women for being creepy and hideous with curly jewfro hair. The most common occurrence is I'd say hi to a girl and try to introduce myself, but they usually put their hands up in a "Stop" sign and say "Nope" or something similar before I can tell them my name. They are also commonly disgusted with a scar on my neck (I was attacked with a knife once) and have no problem voicing said disgust haha. I found out that the teasing doesn't stop with high school if you're ugly enough. Given all this information, I decided to hell with it and just give up altogether on women and put all my focus into my creative projects and making money. I've been doing great since, purchasing a three-story home for myself and paid off the mortgage completely, now I just sit at home working on my music. Ever since I made this decision, my entire family has been looking down on me as some sort of outcast. They say it's weird for a guy my age to be alone, and they seemed to love tricking me into blind dates, which happened three times. The first time the girl was very clearly an addict of sorts and never stopped talking about her cats. The second girl got up and left as soon as she saw me. The third girl was super polite, though it seemed fake, but she was also very very large. I know that makes me sound like a bad person, but physical attraction does in fact matter, as I take care of my body and I don't think it's unfair to expect that in return when you're dating someone. So, because of nonsense like this, I'm often wary of anything any of my family members invite me to. When I assert that I'm not interested in dating, they get audibly upset and begin to berate me. I've already given up on attracting any woman to the point of dating me, I don't blame girls for finding me ugly, I firmly believe you should be attracted to whoever you're dating. But as I said, my family is treating me like a freak and it's really getting to me, making me think I'm messed up in some way. Is it really that odd for a guy my age to already not be interested in dating?
