Update: Thanks for the input, once again you saved me from falling down the wrong path mentally After a shower, meditation, self reflection, and some reading, i realized 2 things: 1. I am not completely over her, and to me, thats ok, I have accepted that its long over, and as you guys said, there is absolutely no reason to talk to her. I have a great life and I am a better person w/o her. 2. The feeling that I got was definitely a kick in my ego, I felt defeated and thus it lowered my self esteem. Guess I'm not a big fan of having an ex flock to another dude. /s

All jokes aside, definitely came out of this as a stronger person. Told me ego to stop being a bitch and remembered all the great things I have going for me in my life. 10/10 would not recommend other ppl going through this.

Original: In a state of deep confusion rn... Desperately need help...i'll try to keep it short:

A while ago I broke up with my now ex(whom i had oneitis for) since she said it doesnt feel right with me due to religion, after which I was depressed for only a little while but soon I forgot about her completely. Since then I've been on diet and went to the gym and picked up self improvement over the last month or so and really got myself together. And I was able to even come across pics of her without missing her or anything, I thought I was finally over her...

But heres the issue, I ran across her today, and we sat down and talked for a long time( we ended on a mutual breakup, so it ended up being just a catch up). The whole time I was extremely happy, because I realized I could look at her without the feelings coming back at all, to me she just looked like another woman

But then towards the end of the convo, she told me that she already got in a relationship with someone else, and he is religious and more musically involved than I was(she was a musician). Which to my surprise, I still didn't feel much, it wasn't until after she told me that she told a mutual friend of ours that she had feelings for this guy a couple weeks before we broke up(granted we were already on a downward spiral).

Then it just hit me, its not anger, its not depression, its not jealousy, but just a weird, hollow feeling. I need a clear insight on this to figure out whats wrong with me to get over it, and I feel like I can't pick myself up completely without getting over this... Please help... Thanks

Tl:dr: oneitis relationship ended, thought I was over her, then realize that she was seeing someone weeks before breakup, left with a feeling of confusion... Need help getting out of it to continue
