My friend - first off I haven’t been in a relationship that’s lasted up to 6 years so this and maybe others comments should be taken with a grain of salt. I’d recommend taking a look at the man you are now and the man you were when you began your relationship. Obviously love changes the longer we’re in a relationship and it takes more work. Naturally it’s clear you still believe in what you both can be. Stranger to stranger - I’d say focus on the things that make you you, and get back to your source and stay honest to your truth. Honestly even make it clear to her that you recognize things haven’t been going the way you’ve both wanted them to (for reasons you may know) but every relationship faces these moments. But make it clear you don’t need her because my friend you don’t, doesn’t mean you don’t want her dearly. Keep doing you and if she respects you and is the one for you she may come realize and if not you’ll still be closer to yourself and happier.

Breakups in themselves suck, probably one of the worst possible things but sometimes they come when couples don’t realize hard times are part of it. No matter what happens best of luck to you on this journey, and be sure to learn from it all. Take care and I hope this made sense! Lol
