Might be irrelevant but, when I've had friends who've felt like this, it turned out they were developing 'strong feelings' for the wrong man essentially.
By that, I mean that rather than taking time to really get to know someone and really considering whether the man was right for them, they fell in love with the newness of it all, the idea of being in love and with the potential that this might be 'the one' - all the fluff.
Then they'd turn the man's flaws back on themselves. Eg if he cheated, or didn't want to commit, or just weren't feeling it, they asked, "What is wrong with me?"
When the answer was there was nothing wrong with them beyond trying to make it work with a man who ticked some of their basic boxes - had a decent job, was clean and well presented (what ever that looked like to them), had friends who loved them, were close to their family etc but completely ignored basic incompatibilities like opposing values, attitudes towards women in general, incompatible interests, lifestyle, life goals, just whether they clicked on a deeper level.or not etc.
Women who reject men for those things are often labelled 'too picky' but many women invest more time, and have more criteria for, buying a house or choosing a career than they put into choosing a life partner to share all those things with.
Rather than hoping a man will decide you are the one for him, really consider whether he is 'the one'for you. Because its very unlikely that all.three of these men were absolutely right for you.
