Souvenir gift for unforgettable one night stand?

I met this single mom she's not that hot but she's still have things to offer still beautiful and doing well in the bed.

Things went wrong between us and doesn't work anymore. While we were together there was moment she was like opening her heart I asked about her family and there was general talk and then she mentioned her brother that died she was going to cry but I just hugged her , I feel it was more than 1 night stand there was moments we were so close to each other she said I like your personality etc. I honestly wanted to take it to another level but that guy showed up when I dropped her home she was shocked and I said who are you? He said just like you I like her too and had sex with her I was like my god she didn't tell me that I just left she kept call me I answered her next day and then I told her I give you 2 choice let's set and I will listen to you with one condition I want you to change and stay with me only she said I will continue my life and I will not change I blocked her every where.

Anyway that night was just unforgettable should I give her souvenir gift?
