I have been there and done that. Loneliness is a hard thing however being with the wrong person is even worse. I married a man who adored me and made me feel like a Queen at first and now he doesn't want to spend time with me. I suggest you work on your self esteem and yourself. Until you become happy and confident with yourself you shouldn't bring someone else into the equation. I have found you it easier to attract the opposite sex when you become comfortable and confident with who you are and you just go out and enjoy life and do things you like to do. Don't be so hard on yourself. You say all your friends are getting married and having children however I believe many of them may end up end divorce. At least that is just a statistical fact. Better to end up with the right person than the wrong one!
