Is it normal to remain single forever and never look for love again

I'm 31 SINGLE male which is quite young but it seems that I've already seen everything I needed to know about relationships and have resigned myself to stay single for the rest of my life.

I've been luckless in love for a long while and it won't get any better now. I've tried relocating to new places, travelling to new countries and registering in online dating sites. The only women who come to me now are the "leftovers" and rejects noone else wants and really most of them have issues that I'd rather not deal with.

It hasn't been always like this: in my early 20's after college I felt like I owned the world and that was a period I should have really got settled down. BIG MISTAKE - I broke an engagement "because I felt I wasn't ready" and needed more breathing space.... I avoided a lot of girls that came to my life during that period because I had to get a good job immediately as my little brother needed attention and financial help because of his disabilities. Also my mother who has no means to support herself financially.

Almost 7 years have passed by now. Even today I'm not free from bad loans and financial problems but it's way better than before: I don't want to be the person who runs away from his responsibilities. Almost all my time and energy is consumed at work so I can save up something. I've been visiting nightclubs and other seedy places but they're a dead end and nothing good can come out of it.

I don't complain because I no longer have the energy or desire left to be in a loving relationship with a woman. Well most of my friends from college days are now settled in their lives and have popped out kids - I do envy them but it no longer seems possible in my case. I really HATE IT when they "advice" me to get settled down - it's like rubbing salt on my wounds.

Years of working in shitty desk jobs have turned me into a boring sort of person with no social skills around women (which is complete opposite of what I was in the early 20's). I wasn't single the entire time though: I did have several brief flings and affairs which mostly lasted a month or so but somehow fizzled out in the end and consumed a lot of energy in the process. My last affair lasted 12 months but this girl eventually broke my heart and left me to carry the can. It was a big loss for me because my feelings have been badly bruised and I'm no longer able to trust women in relationships anymore.

Fortunately, I've stopped seeing that bitch now but she does SKYPE me all the time. All women I meet nowadays are so SELF-ABSORBED (not that it's a bad quality, I'm like that too) that they have no interest in someone like me who isn't confident and doesn't earn that much.

I had become very depressed and lonely and spent all my spare time drinking and smoking. I even had suicidal thoughts for being such a failure. But then something occurred to me.

I figured out women aren't worth losing sleep over. So what if I were to die single, there's a lots of things I can still look forward to. I stopped smoking for 3 months straight which was a huge health benefit as now I'm able to climb a flight of stairs without exhaustion. For the last 2 months, I was able to spend time earning more money, was able to travel to new places like Europe and South East Asia. I really feel a lot more positive now and I'm suddenly able to meet more women again during my travels. But none of them show sexual interest in me.

I have a lot to look forward to in my remaining life but being in a relationship seems distant and unlikely now. So really, with a positive frame of mind, I'm about to throw in the towel. Once I really QUIT, I feel lasting peace. No more mind games, no more uncertainties, no more heart breaks. It may sound bitter but I have to survive my life and find happiness. I have to live with the fact that women will have ZERO contribution in my future happiness.
