Petal, I feel the same way. I will be 39 in Feb. (On Valentine's day no less). I have never been married or even came close. I have not exactly given up, but have tried to come to terms with the fact that I will probably be alone. Not in a Oh poor me way but a practical take care of business way. I bought a house, put away for retirement and all that.
Admittedly my last relationship was not healthy emotionally and was over about 5 years ago, and I was extremely wrapped up in caring for my mom for the past 3 years so was not really looking or ready. Now, if it comes, great, if not that's Ok too. I have too many single 30+ girlfriends who still live in "When I Get Married" Land. They are sitting on a shelf and waiting their lives away. I really can't stand when they and married women tell me I am fooling myself that I can be content alone.
I do get in the dumps sometimes about it, but not like I used to when I was younger, life's too short. Tomorrow is another day. Hang in there. (((((hug))))
