Sounds like you need someone better in your life.

You haven't mentioned still being smitten with her which is a positive. Time to move forward & find someone else

She probably saw better choices on Tinder.

Three years and she’s still titled girlfriend? Maybe she was ready for a relationship that is going somewhere.

Well, maybe that is her way of dealing with the breakup although, I know, it really hits a person in the guts if you are still in love with her. At least now you know where she stands. Sometimes hard closure can turn out to be the best thing that ever happened to you. I speak from experience.

Well, she waited till it was over, it counts for something. I'd guess the feeling was gone for some time and that's it. Happens to lots of people, you'll be fine

just think, she probably boinked at least 3 people that very night! lol

she was probably on tinder for a long time before that

I mean yeah that sucks but why do I get the feeling you're more upset that she broke up with you nicely than the fact she broke up with you? Would you rather she had been horrible about dumping you and told you to screw off? She told you she wasn't sure clearly she was trying to let you down easy.

I’m sure that hurt, a LOT, but it’s better to be done now than in years from now when y’all are even more entwined. I’m sorry for your pain, this too will heal
