Boots77, I came on here after a rather large argument with my husband, looking for some comfort from somewhere to show myself that maybe I wasn't alone in how I'm feeling, and came across your post. Wow, I could have written the first two paragraphs myself.
I couldn't quite articulate it, especially when in the midst of a heated argument, but all I could keep saying was 'no one is hearing me. I am not coping!'. Hubby doesn't understand exactly what I'm not coping with, and honestly, neither did I really, until I read the topic of this forum. Lightbulb moment!
Anyway, I don't have any advice for you really, but hang in there, I do try to remember that life has seasons. They come and go and change. Some seasons are cold and lonely, and others are bright and warm. Just gotta get through the bad to recognise the good.
