Issues with men and relationships

I have an embarrassing problem. I grew up in a sheltered environment and attended an all girls school as a child/teenager. I never really socialised with boys until I was around 15 years old. My father alternately mocked me for any crushes on boys I got and encouraged me to wear revealing clothing. I didn't realize this was weird until I left home for university. I have had one boyfriend who treated me poorly and a couple of brief flings. When I was 21 there was an incident where my father came into my room naked while he believed I was sleeping and slid his hand under the sheet and touched my breasts. I was terrified and baffled. When I told my mother he blamed me, saying I should not have been looking. Now, I have tried to move on but I live a life in a small village where I don't get much opportunity to socialise with men my age. I find that I am developing unhealthy crushes on men who are even vaguely nice to me. I know in my rational mind that this is stupid but I find myself fixated on a much older, married man who, typically, is mildly flirtatious and has shown sympathy towards me. I'm ashamed to tell anyone or get help so I would like to ask, you, the internet, for help. Thank you in advance for any advice you can give about overcoming these issues.

It was stupid on your father's part to act the way he did! Anyway, your real issue seems to be self esteem? We go after unhealthy crushes when we feel thats all we will get. Work on yourself, keep telling yourself you are good enough to get better than that. Only when we stay away from unhealthy relations, healthy relations can make their way into our lives.
