Inky,

I've been there too. Just didn't have enough self-confidence to say no to someone that I trusted. It's hard to say no to somebody who really wants something, even when you are uncomfortable or worse. Still, he had no right using you like that when you didn't say yes. If you had been able to say no (and if you can learn to for the future) you may have been able to save yourself some heartache and grief. But it still isn't your fault.
