Back story - been together 15 years and have 2 DC ( 8 and 12.) He was so kind and funny when we met. However he has become permanently distant, grumpy, stressy, and a little bit mean to be honest. We have no sex life, he moved out of the bedroom 4 years ago saying I snore. I probably do, but so does he. We haven't had sex in probably 7 years. I know the kids can be stressful, I know his job can be stressful and I have been patient and understanding, at the back of my mind thinking that when the children are older we will have the time and space to work on our relationship. Anyway, I thought I/we had made progress since last year I persuaded him to drop a day a week, we are lucky enough to be able to afford it. I had visions of child-free walks, pub lunches etc, and getting back on track. I was soon disappointed - he has consistently been spending that work free day in his home office, busy. I'm not sure why but a few weeks back I installed the web safety app we use for the children onto his work PC, it tells you what websites have been visited, etc. I now know that he spends the day browsing porn, with the occasional burst of 'legitimate' activity eg renewing insurance, before returning to the porn. I don't feel upset. I just feel kind of icy. I think I'm done here. Would that be unreasonable?
