Search Results: he has feelings for his ex

So here is my dilemma, I am talking to one girl I know since the corona lockdown. We had a really good tuning , conversations. Due to corona, we were in different cities but we enjoyed phone or video sex too. Fast forward to this month, we happened to be at same place, so we really enjoyed with each other and I really felt good vibes. until this point we were just friends who were being sexual as per our convenience (no string attached kinda) . But this time, we both felt different maybe because of conversation thing. In my past, I had few casual relationships and one during lockdown as well. Anyway, the thing is she has cheated (makeout with two guys , no sex) on her ex boyfriend in the past when her relationship was going through a tough patch and it was about to end. But, she ended them in some time as well. As per her, she also does not feel any remorse for whatever she did. She justifies them citing lack of emotional availability or bla bla. In her past relationship when things got better, she had the guts to ask her ex for marriage on one or two occasions, without feeling anything for what she did behind his back. Anyway, fast forward to present, I like her really but in dilemma to ask her out for serious things. I don't want that cheating to happen to me. Also, she kinda gets upset with my past casual affairs but never takes the blame for her misdeeds which makes me rethink about her. Sometimes, I wish us to be good friends like earlier, there was lot of steam that way without any judgement
