I'm exactly the same as all of you here. Nothing more than friends for 10 years now, and tbh not even that. I don't really like him and we do everything separately, which suits me. But here I am plodding on 'for the kids.'
Not yet 10 years (feels like it). I can totally relate to this. I have a primary aged child with SEN and a younger child - I don't feel in the right place to cause an upheaval.
Attending therapy (about something else) but constantly discussing my relationship with my husband and how poor it is. It feels I can't make a decision that will impact so many lives (my dc), so yes, in many ways if something major happened it would almost be a relief.
Husband's porn viewing has played its part. The deceitfulness attached to this as well (secretly viewing), I just don't seem to be able to move past it (he has absolutely no remorse and called me a prude). I've realised our values are different too. Entering perimenopause seems to have heightened everything - it's like I coped before with many irritations but have less tolerance now.
I feel alone in terms of I would love some emotional support and affection (I'm trying to work on being my own cheerleader etc.) I don't have a wide circle of friends and no-one who I feel I can tell about this. Burying myself in ironing/housework and hobbies and focusing on dc...distraction I suppose (apart from dc who are my main priority and not distraction). Only males left extended family wise and not sympathetic.
In short, no abuse, support in practical and financial ways. It's not enough but it has to be (at least for now).
