because I can't sleep:
Girl meets boy
girl thinks boy is kind of cool
girl flirts with boy
boy flirts back
boy proceeds to yank girl around
girl forces boy's hand
boy says: let's be friends
girl considers this for a few weeks
boy yanks girl around some more (see Second Method, below)
girl decides people who yank her around are not her friends
For those with a similar story, here's something you'll LOVE:
Before becoming aware of this person's loathsome feelings of tenderness you may have occasionally flirted or complimented them. In order to undo some of the damage this may have caused, you may wish to become distant. There are actually two ways to go about this. The simpler is an immediate and complete cutoff. Treat them coldly, show no interest in conversation, and make occasional criticisms or thinly-veiled insults.
The second method for becoming distant and reversing past kindnesses is an unpredictable and disorienting variation in the nature of your interactions. Be inconsistant in how you treat the baffling individual who seems to have devoted themself to you. This keeps them guessing enough that you don't have to worry that they're falling deeper, and may lead to less guilt on your part since you are not being constantly cruel. Some examples and guidelines:
* Try greeting them enthusiastically one day and with complete boredom or disinterest the next.
* Say or do something thoughtful or sweet, thus encouraging your adorer to think that you do, in fact, value their friendship. Follow this up within a couple days with a callous remark; an off-handed delivery will lend it the most impact. Some sort of statement which implies that they are wholly extraneous to your daily routine should provide a good contrast to prior instances where you went out of your way for them.
* Physical contact is perhaps your greatest weapon. The tiniest of touches are most likely of a near-intoxicating character for your adorer. Pepper your interactions with touch very sparingly to make sure each is considered incomparably precious. You may want to knock them off-guard with something tremendous like a fervent embrace, or an extended head-scratching session, or by dancing closer than a "friend" would. Then, in a difficult time, when they clearly need the reassuring hand of a friend, neglect to offer it; shrink back or respond in a lifeless manner if they initiate contact uninvited.
* It's difficult to say what the most effective ratio of nasty to nice treatment is. This will depend on the exact nature and history of the non-relationship, so you will have to use your best judgement.
