Maybe this isn’t helpful, and I’m sorry to generalise.

Ten years ago I could feel me and my now ex drifting apart. I fought it with every fibre of my being. I did everything I could to keep us together. I shelved my personality to keep her happy. In the end, she broke up with me, and 2015 was my worst year ever.

Since then, I grew a lot as a person, figured out who I am and what I need. I feel much happier with just the self awareness. I still talk to my ex sometimes, and I can’t imagine being together. Not to disparage her, but she’s so damn boring now (to me). I’m sure it’s mutual. I am glad that we broke up, in the end.

I don’t know where you’ll end up, it might be exceptionally painful at first, but you might end up better in the end. I do feel for what you’re going through, it is very very hard.
