There are many reasons, or sometimes, excuses, which I often give to people as to why I have an aversion towards relationships, marriage and having children.
1) Love makes people blind AND STUPID. 2) I don't do relationships. 3) I'm philophobic (an irrational fear of love and intimacy). 4) I can't commit. I'm a commitment-phobe. 5) I'm not good with kids.

Though the abovementioned excuses may be true, I think that the real reason I can't do it is because I'm afraid that someday I'll end up like HER.
