Do not settle, you will be unhappy later. I used to settle a lot for unworthy people and was always miserable. You say that you are not attractive, but that is still no reason to settle. If being unattractive makes you unhappy, do something about it! Work with what you got, wear flattering clothes, make-up, even diet if you want. Also be careful of men who are going after you because they think that you have no self-esteem or that you might be desperate, they can get controlling...they think that you cannot do any better and you will put up with their shit. It is the same with beautiful women and ugly guys.
