Hi ifdanny
Welcome to the forum.
I felt so much like you do well still do at times. I am 47 daughter nearly 15 but felt invisible like you. I live still with OH but living now seperate lives, I had started to feel like you, nothing in common with OH, always the one to arrange things to do together, when OH didn't really seem all that bothered. Lost a lot of confidence. Just beginning to feel better about myself so do know how you are feeling.
Hope you can sort things out with your OH. I found everyone here to be so helpful, so understanding. I Hope you can meet up with new people in your area, i am about to do that myself. Starting to feel more hopeful, do hope you will start to feel the same soon.
best wishes
