You don't have to do anything. You should have an open heart and love will come knocking on your door. You have to patient since everything has its time. Since you have not found a man, it does not mean you won't find love. You just have to wait for the perfect moment.
dont go looking for a man.when the time comes god will have mr.right come along.when u rush or try to find some one you get the wrong person in your life.dont go looking let him come to you.theres a somebody for everybody.
At our age, the dynamics of love changes. It's no longer just about flirting, looks or sexiness. It becomes more about the company and nurturing. In other words, it starts it off from the other end.
Older guys respond well to people who encourage us, compliment us, don't judge us, don't tell us what to do, let us make mistakes, assumes we are fully functioning adults, yet provide hot home cooked meals, help with the minor routines of life like cleaning, laundry, shopping. Give it a try, it seems like a lot to do for someone you barely know but like I said, you have to start it off from the other end. :)
