Ok, once again I'll come in late with an added perspective. And being far older than you Matt L and still single, I know much about going through life with no love, family, or success in finding a mate. The others make a few valid points I'll reiterate first.
A man matures, changes, and generally improves with age. He can and should at least. Young as you are, you have potentially many jobs, different living environments, and female encounters to look forward to. And as you get older, wiser, emotionally stronger, and hopefully better as a person, you may find a permanent successful relationship that leads to a normal, happy, family of your own some day. Thus, don't consider the game over yet when you've only just begun to play. You're in your prime through your 20's, 30's, and 40's, so no feelings of relationship failure permanency in life are warranted until you enter your 50's or 60's at least. Since situations and people change, your future outcome is not necessarily dictated by your past and present conditions. I'd suggest that that you recognize the time scale of life far beyond where you're looking and living now. Doing so leaves room then for realistic optimism that you very well can and may find a good wife to help carry your genes on. My own sister didn't marry and have her first child til 42, with a second one at 45 - a bit late and challenging for a woman perhaps, but not so for a man. My brother didn't marry til he was in his 50's. And I have 2 american friends in their 60's with young Thai wives. Life is full of surprise encounters and relationship possibilities. You have many to come, both good and bad, so stay optimistic and embrace good changes that may improve your life circumstances.
Being alone, single, and too old to consider being a father, I have my own feelings of disappointment in not passing on my name, good genes, and values in life that mean a lot to me. All my great career awards, pictures in life, prized possessions, and personal momentos are set to be thrown in the trash when I die. I have no one who cares or would want any of it. No one to care about me when I'm old and decrepid, and certainly no one to miss me or tend my grave when I'm gone. That is the sad reality for those of us without family, but I'm far more committed to that destiny at my older age than you are. The thing is though, I don't judge my life's worth on that one category. Sure, having no family is a huge deficiency in life, but it's only one part of the package we inherit here. And in my case, I was blessed with an extraordinary career and outdoor life of trips, fun, and adventure, along with many good friends along the way that I've tried to maintain. Still, even these things are not the standard by which I judge myself as a success or failure. These are all worldy, temporary things that make life more or less enjoyable for us, but they're not what define us. At the expense of making some folks uncomfortable for a moment, let me make my final point.
Our entire purpose in life is to know and love the Lord, and to serve him by loving others. Making your life count, being productive, and living a successful life is NOT determined by your career, finances, social status - or family. These things certainly affect how we live life for worse or better, but they aren't the final judge of who we are and what we did with our lives. They do not determine whether we are a success or failure. Understand that, whether you find a mate in life, have a family of your own, or not, has little to do with whether you're a success or failure. If you want to be a success rather than a self claimed failure, then lead a productive life of focusing on your creator, Lord, and savior. That's the number one relationship that matters. Girlfriends, family, friends, and others come after that. When you have the first relationship right, it really helps instill a feeling of self worth and confidence, along with the strength to guide us through life's disappointments and challenges. And usually, the other relationships become more numerous and worthwhile too. It's a good path to be on in life. You needn't be or even feel like a failure from any of life's circumstances. Success is available to us all from God. You just have to let him in.
