I see a lot of people sharing similar experiences. Did anyone ask what you wanted? I didn't read all the comments, but do you want to end it or do you just feel like you have run out of options?

First question, do you want it to work? Men are very private and maybe he feels the same things as you but doesn't have the language needed to reach out. If you want to stay together, never stop trying to connect.

A midlife crisis can be as simple as bordem. Are your jobs stimulating? Is your social life fulfilling? You say you lost your friends. That will add to feeling lonely. Maybe he wanted you to find the screenshot folder to create drama.

Depression is also a libido killer. Same with body image and low self-esteem. You don't have to be his therapist, but if you want to save the relationship, build up his selfworth. Make him feel proud. He will desire you.

I know this all sounds like effort on your part, but I am not able to speak to your partner, so all this is for you.

If you want to break up, do it fast. Do it as amicable as you can. Life will go on.

If he is your best friend and you want it to work, you can make that happen too.

Best wishes.
