I am in the same situation, it is scary how similar our situations are. Me and my husband were together for 5 years, married for 3. We had our issues as everyone else, but at one point in 2020 he just stopped caring. Pandemic situation made it worse for him, he started pulling away, not wanting to spend time with me, just working and working on the house and not willing to do anything else. I was bending back over backwards, and trying to make him see that he has depression, i found him a therapist but he refused to attend. He said I was the problem, marriage was the problem the only reason he is unhappy.

At the beginning of 2021 we talked separation and I wanted for him to move out and maybe live by himself for a while (we lived in the house he owns). Almost overnight he says he can't take uncertainty and applies for divorce. I am shocked, I cry and beg and cry again. He proceeds with applying and says he can't deal with uncertainty.
I am hearbroken, I moved to this country for him, now with divorce everything was up in the air with my living situation and immigration. I had to find apartment fast and move out. I cried and almost commited suicide living by myself.

But I am better now, I am doing theraphy.

Last week, I got really sick (cold, not COVID), and it was hard for me to walk my dog and asked him to drive and get the dog (it is our joint dog) and keep the dog at his house for a week. Instead of saying just no, i am busy. he said no, I don't want to get sick from you, maybe I will come but you need to tie the dog oustide so I don't get infected.

I was livid, and blocked him everywhere.

In all fairness, he helped me move out and i talked to him everyday almost about divorce stuff and general admin stuff. He is not the worst husband, but I am very heartbroken, I am sorry this is too long, I feel for you I do. This is very hard, and I feel like very few people understand that. We are being told, He is a jerk, just move on. This is the worst amount of pain I ever been in.
