I went to MC with my H. It was helpful in that it clarified for me that I needed to end the marriage, which I then did.
Session 2. The counsellor asked us both to say the thing we most admired about each other.
I went first. I said the one thing I admired most was his bravery in standing up and speaking out, against the wishes of his family, about a really important and deeply personal issue.
The counsellor nodded and then turned to him.
"Errrr... she's really good at reading and that so if I've a letter I want wrote, I let her do it."
Seriously.
There were so many things he could have said.
I'd left my old life and moved to a city where I knew nobody, to be with him
I'd worked my tits off to get a decent job to put food on the table for him and his son
I'd created a new role for myself at my work, pitched it to the site manager and got it
I'd put aside my feelings and pain around my infertility and not let it affect my relationship with his DS
I'd encouraged him to take driving lessons and bought him a car when he passed
I'd taught myself web design, Excel and various art-related software
I'd lost 4.5 stone in order to qualify for infertility investigations
I'd given up smoking after 15 years at 40 a day
(all of the above while we were married)
But no. The only thing he could think of was that I was more literate.
As I'm writing this, I'm realising just now that the list, to him, wouldn't have been admirable, they would all have been negatives. Because he could only see things as they reflected on him, and all of my successes, to him, simply showed that he was unsuccessful.
Whereas he was comfortable with me being literate, because he was dyslexic and therefore it wasn't his "fault" that he wasn't confident in reading and writing.
Sorry OP that was very self indulgent of me. Obviously after 15 years that "she's good at reading" still burns. Maybe I can let go of it now.
From an observer's viewpoint, it does sound a bit like you know you need to move on but you don't want to be the "bad guy" and break up a relationship that's not terrible but just isn't that good either. Do you need to give yourself permission to end things and seek happiness for yourself?
