Search Results: dated two girls at once

Does trying repeatedly in an assured not desperate way work with girls?

Here's a little context in a situation I found myself recently. Started seeing a girl, took her on a date, and made out with her numerous times when out socializing and stayed at her house and she was interested.

Recently she has went a little cold, was flaky about a second date but continued to text me, i've found out she has been seeing another guy which is fine as we are both single and I do the same. As such I assumed she was not interested anymore. As a result I went no contact. She then contacted me twice when drunk. I'm not too sure whether she is seeing the other guy but I have not contacted her and have talked to her once in a social setting.

Past experience has taught me to move on to another one in such situations but I'm wondering did I give up too easily in this situation? She has always returned my texts but when hearing about another person on the scene I instinctively withdrew as she was not as responsive as before and as a measure to protect myself considering I was invested in this girl.

Is it worth it giving it another shot which is now two weeks on or leaving it?

Sometimes I wonder whether or not if I tried harder I may have succeeded further in my attempts. On the flip side when she went a little cold I perceived pursuing would not have helped the case.

To persist or let it go?
