I'm mid 40s. I had a 15 year long sexless relationship/marriage that ended a few years ago. Aside from a couple of short things here and there (that I've ended) I've been single ever since. I've never had a relationship where we were really 'together'. I don't know where I'm going wrong!
No one is interested and never really has been and I don't know why. Since my marriage ended, the only men who've shown any 'real', sustained interest have been married/unavailable - I don't encourage them. I don't remember the last time a single man showed any interest in me 
I suppose I just can't see where I'm going wrong.
I've been a size 10, I'm now a 14/16. I think I've got a reasonable figure. I do have a bit of a tum and wobbly thighs at the moment. My bum is always curvy. I'm not particularly body confident, but I don't shy away from things either. I'm average looking but make the best of myself. I don't wear much make up but often get told I'm lucky because I don't 'need' it. My hair is ok. Yes, I could tone up and lose a stone+ but, I know from experience, that isn't the problem. People often assume I'm younger than I am. So I guess I don't know what I can do physically/appearance wise.
I'm an educated professional; I play a few musical instruments and I've recently joined a new band and will be gigging shortly; I swim and do yoga; I used to do swing dancing, but that's dropped off over the last year or so; I'm probably slightly 'alternative' - still wear DMs and long floaty hippy skirts, Birkenstocks and make my own jewellery. I'm open to new experiences and like to take on small personal challenges. So I don't think I'm 'boring'.
Recent 'compliments'/comments/observations made by others, men and women are that I'm: lovely; kind; warm; easy to talk to; funny; don't take myself too seriously; pretty; sexy; cute
; patient; romantic; loving. I've been told more than once that I'm the "right balance of sweet and sexy". I've been told I'm a good listener and that my advice is good. So I don't feel I have any major character/personality flaws that are putting men off.
Just no one ever seems to find me attractive/fall in love/ fancy me/ask me out.
I know that people post on here and other people can see what is wrong or offer explanations. I just suppose I wonder if anyone can shed any light on it.
I'm quite content being single: I do things on my own and am fine doing so, but I would like to meet someone. But clearly there is someting about me that puts men off and it's never really been any different.
I've tried to focus on the positives here. I'm quite happy to provide a list of my negative qualities! But I don't think it's helpful to focus on the negatives really. No one is perfect...
