We matched on Tinder of all of places. First date was just a walk at a park and a long conversation. We slept together later that day (night). Later found out I was only the 2nd guy she'd ever slept with as she had gotten out of a 7 year long marriage several months prior. She wasn't intending on sleeping with me so quickly but was just very attracted to me in multiple ways (her ex was a Dbag, so just me being nice and treating her well was a big deal to her). We became friends and had a sort of relationship. I say sort of because we never took photos or went on real trips together, but we talked, hung out, texted every day, went to movies together, etc. This went on for about 7 months. Kind of throughout I felt like a) I'm attracted to her, but not wildly so, b) we seem to think in fundamentally different ways on a lot of things and kind of in general, and c) I like her, she's a good person, but I can't really see myself ever being in love with her.
Over the last several months I randomly and inadvertently started developing a very emotionally intense relationship with another woman, and it just kind of highlighted to me how I don't have those feelings towards the girl I'm actually with. I ended up breaking up with her last night, she was devastated and cried a lot, and I feel horrible. She's a really good person, super easy to get along with, no drama, but for whatever reason, I wasn't feeling much chemistry at all, more like FWB vibe for me even when I tried to think of her as more than that.
I'm distraught. I feel a sense of loss, and I feel horrible about hurting her. She doesn't deserve it at all.
Anyone been in this situation, in either position? Just feeling bad and kind of confused right now...
