If you are single and looking for a long-term relationship or marriage but are having trouble finding a partner or spouse, here are some suggestions for you - and they don't involve an Internet site.
 
First, do you know specifically what kind of person you are looking for? What qualities do you value in a mate, and how do you judge whether a person has those qualities? 
 
Do you have a clear picture of what your relationship with your partner will be like, including how you will treat each other, how you will deal with conflict, what your social life will look like? You see, the clearer your values are and the clearer your picture of the kind of person you are looking for, the likelier it is that you will end up with what you want.
 
Do you have issues from your family of origin or other relationships that might prevent you from enjoying this kind of happiness?  Would some counseling or group support help eliminate these obstacles?
 
Finally, do you live in a way that is consistent with what you want in a relationship? Because in the end, it is far more important to be the right person than it is to find the right person.
 
You can't attract anyone who is better or more successful or kinder than you are comfortable with, or believe in your heart of hearts you deserve. If you work on your mental pictures and your growth as an individual first, you will recognize and be ready for the right person when that person comes along.
