Man, this is a great thread.
The problem is, I have an entire list of funny reasons why no one should date me AND an entirely different list of serious reasons why no one should date me, and I'm not quite sure which one to post.
I guess I'll go with the serious ones, since a lot of people ask me why I'm single:
1. No one should date me because when I meet all his female friends, I will be sizing them all up and wondering why in the hee haw he isn't dating any of them, and I will assume he is missing out.
2. No one should date me because I won't tolerate controlling, manipulative people (even if it's his own mother.) If he already knows how to stand his ground, great, maybe it could work. But if he lets them run right over him and won't stand up to them, I will--and it won't be pretty.
My two most serious relationships ended partially because of one mother who tried to manipulate and another who wanted us to become Jehovah's Witnesses and wouldn't take no for an answer. It did not go well in either case because I'm obviously not kinda gal who listens when someone says, "Just shut up and do what I say!"
Even at 18, I held my ground, so you can only imagine how much worse I've become with age.
3. No one should date me because I think God has assigned me as The One Who Helps Prepare Them For a Girlfriend, But Not The Actual Girlfriend. Almost every guy I've talked to in the past 10 years has met someone else either while he was talking to me or soon after, and in some cases, even got married.
Therefore, I usually tend to keep a guy at a bit of an arm's length away... even if I really like him... Because I often expect that he'll wind up with someone else anyway.
