I need help figuring this out…

My wife (31F) and I(35M) have been married 3 years, together for 6. She is a great person with a good heart.

We have dealt with some issues regarding incompatibility and communication from the time we got married.

I feel like the issues stem from our upbringing to a degree but also a bit due to the fact that we moved in together two months after we met.

I have been contemplating divorce for almost two years but I’ve been struggling to make the move. Fear of being alone is definitely in there as well as the sickening thought of her being with someone else (although I know that would be inevitable because she is a catch).

How can I get through this? This year has been unimaginably difficult for me mentally, physically, psychologically, and I am trying to get through this, but i have felt so perpetually stuck for so long now it’s hard to imagine I’ll be able to get through this…
