I'll forever be alone.
Are you sure you'll never find someone in your life?
As a man, it's harder to be in relationships. Women are so likely to cheat, and I don't like anybody.
I understand how you feel, but you should stop complaining about how your life is unfolding. Try to be more positive and maybe you'll end up meeting someone that you really like.
I do like this one particular girl but I feel too awkward to talk to her.
You will missed 100% of the shots you don't take. Take a leap and try talking to her. You won't know the outcome till you try.
