Search Results: attracting the wrong guys

i meet this girl at my local pub who works there as a server and talked to her a few times , i wouldn't say were necessary friends yet but feel there is potential for something. i enjoyed meeting her and very attracted to her but its weird cause i know she is close friends with the girl who rejected me earlier this year.

had also meet her through her work and talked to her there many times , she had worked at a gym though. but then when covid hit it closed and when i tried to keep in touch with her outside the gym she ghosted me and haven't heard a word from her since.

not sure if she'd care that i'm now talking to one of her girlfriend's and attempting to develop a friendship with her instead. some girls obviously would not care but others might take it the wrong way and assume the guy was doing this to annoy her or to hurt her feelings by trying to get closer to the friend and perhaps get with her.

My girlfriend cheated on me initially but I forgave her because that time she was genuinely sorry and we were not that serious.

But now she cheated on me a second time and expect me to forgive her a second time. I did tell her that I forgive her but in reality I didn't. I slept with her sister last week ( her sister knows what she did to me and she is on my side ) and her sister and I have always had a little chemistry but I never acted upon it because I wasn't a cheater

So do you guys think what I did was reasonable or was I in the wrong? My girlfriend found out I slept with her sister so we broke up and now I am thinking of making her sister my girlfriend. They both had a fight as well. What do you think , is this cool?

just to be clear , I am not gonna date her sister just because I want revenge , I had my revenge. I wanna date her because :

1. I am genuinely attracted to her more now that I found my girlfriend never really loved me
2. I want a rebound
