Why have most of the girls I've dated/tried to date treated me like crap?

I didn't date in middle school or hardly highschool, I started in 12th grade and ever since, every girl I've dated or tried to date either: leads me on, ghosts me, acts like I don't exist, or cheats on me, I don't go for girls that have a bad reputation either, I've always stuck to ones who seem decent at first but I've just never been able to find a good one to date for more than 6 months
