I don't understand why people don't get this.
I have no issues in my marriage at all really. I've been married for many years, my DH is great and I like spending time with him. I do need time on my own in my house though, and when covid hit I didn't get this alone time. Some people just need complete solitude sometimes, just because it's the way they are and the way their brain is wired.
Did I mention my frustration at the lack of solitude to my DH? No I didn't. Not because I secretly hate him, because he is abusive, I am depressed, need counselling, am scared of him or denying my own feelings, scared to speak up or any of the other bizarre reasons stated on this thread.
I didn't mention it because there was fuck all he could do about it and I didn't want the way I feel to hurt his feelings and make him think that he was unwelcome in his own home. His hobbies were all cancelled and office closed anyway.
To those saying the OP can have friends over when her DH is there - it's not the same, having a gossip with friends when someone else is in the house, even if you know they aren't actively listening. Getting alone time by walking around the streets or going to a coffee shop isn't the same either.
I used to do yoga and mindfulness when I had my day off pre covid, but couldn't do it on Zoom when my DH was home all the time because I couldn't relax properly with someone else pottering around in the background. DH is considerate and stayed out of the way but it's not the same as being on your own. It really isn't, and I am lucky that I have a big detached house with study and garden. I just like to sometimes know that I am completely on my own with no other adults around. I need it for my mental health.
There really is no solution to the OP's issue apart from life returning to how it was pre covid, and even then she can hardly go back in time and get her maternity leave back.
