I’ve felt unhappy in my marriage for what feels like a really long time. He is a really good man and a great dad to our 3 boys. I could do so much worse. But he has a tendency to be very negative and critical and I feel constantly nagged and told off like one of our children. In response I’ve become snappy, cold and irritable which I hate. Over time I’ve felt worn down by it and increasingly more frustrated and irritated. I don’t find him attractive anymore and try to avoid being intimate. We’ve split a couple of time in our 15 year marriage but we agreed to give it another try when he’s promised to try and be more positive and less grumpy. I’m feeling very stuck as we have a big mortgage and ty children. He will be absolutely devastated if/ when I tell him how I feel. I know I need to tell him but I’m terrified im making the wrong decision and that I’ll regret it. Maybe it’s me that is the problem and I’ll be even more unhappy on my own? It feels so scary to consider being on my own- but also exciting and liberating!
