If I show clear interest in a girl and she plays hard to get and eventually starts fucking another guy I should be done right?

Curious to see what girls and guys say about this cuz like the past 20 girls I’ve shown interest in did this and I’m really not sure what to do about it anymore at this point. It’s not cuz they don’t like me. I’m pretty sure they find me really attractive but assume I just want sex or something. What do u guys think? If I refuse to date women who have done this I’m essentially eliminating 95% of my dating pool. But If I don’t eliminate women who did this do I still have self respect? Discuss
