How do you know it is right?

I have to say I am kinda easy to fall for a tall dark and handsome man, however I was previously married to a deadbeat for 8 years and now that I am single, it seems I fall for as I said tall dark and handsome men or even not so handsome but they have all the right inside personality to make a girl see him as handsome. I have recently met someone who is handsome, not gay however is kinda feminime in some ways but he is a single dad of a daughter and son, however I like him a lot but no matter who I meet it seems I am always looking for something better and there is no man that satisfies me completely. I need help to find be able to find the right man. Maybe it is because I have been so miserable in the past however, I want to know what makes a person happy with their companion.
