Hi, I have the same problem. I know exactly what it feels like to get no attention from girls. I'm 24 now, and there seems to be no improvement in sight.
But here's the thing. Do you honestly think that just by getting a girlfriend magically fixes anything?
For example, I had always thought that I was unhappy because I've never had a girlfriend, had no money and was still a virgin.
Well, with a bit of luck I somehow managed to fix two of these problems, and my assumption turned out to be rather foolish and naive.
Having money doesn't fix your personal insecurities and definitely doesn't make you happy.
Sex and the whole virginity thing is severely overrated by society, you'll realize eventually.
As for relationships.. I don't know for sure but I stopped idealizing it.
Still, it was such a valuable enlightenment to realize that sex is no big deal and that, theoretically, I could get it anytime I want (by paying for it that is...). It didn't make me feel better at all, just opened my eyes that the problem is of far deeper nature. One that wouldn't be as easy to fix by simply completing a silly achievement.
But this is like, just my point of view on it man
