OP, I must ask you if you wanted to be with any of these men? Because from the way you've described some of them, it seems you were making do with what was available
A couple of them of them I did. I've only dated 4 men in the past 8 years because I'm actually quite picky. I turn down far more men than not. The last was someone I really had wantd it to work with for many reasons but it was really obvious that, whilst he liked me and found me attractive, he was also a bit ashamed of me and, I suspect, worried about what other people/men would think of him that I was the best he could do.
the men I dated preferred their idea of me rather than the real me, I was never able to live up to their expectations of me, and I was not happy to contort myself to meet their idea of me. I refuse to compromise myself just to be with a man
Yes. This exactly. But i would like a relationship that lasted more than a few months if I'm honest.

Maybe you have a point there. But surely there are men who are ok with a woman being an actual person?!

Yes. I'm really struggling with it though.
I'm fed up of being alone and lonely. I'm fed up of feeling there's something wrong with me and that if I were different it might be different.
I don't find the advice to have therapy useful - there's nothing wrong with me. Nor to he happy on my own. I've done that and I'd like a relationship. A proper one. With a partner.
And I'm just really bloody frustrated by it.
So many women saying that a man has never commented negatively on them in a relationship. I just don't know how they do it 
I just wondered to what extent other women also experience similar really. And if there was an explanation beyond "you must have low self esteem" because I don't.
