When I told my daughter about this post she said " Mum I didn't know you posted on Gransnet!". So here I am replying.
I too will "celebrate" 50 years this summer. with a family get together and old friends, Covid withstanding. It has been a long, sometimes very unhappy, angry, verbally abusive and controlling period. I stayed for various reasons: financial, the children because he threatened to take them from me if I left and told me I could leave with what I stood up in. My grown up children know my life with him hasn't been and still is not easy but I think that "surviving 50 years" is something I can acknowledge, knowing that I kept the family unit as safe as possible in my hands. The grandchildren adore him so I can easily pretend again that I can "do" another family get-together and just go on. I'm sorry to hear that your marriage is a loveless one. Is he open for discussion, listens to how you are feeling? [Mine isn't and will never change]If not and if you feel there is nothing left for you to save, reclaim or change, then you have some important choices to make. My best wishes for your future.
