<human>: So back story: I am 18 and the guy is 19 and we go to the same college (that is a VERY expensive college). My wonderful father pays my tuition and living expenses and asks for nothing in return except for a few things: that I not do illegal drugs (he's even okay with alcohol as long as I do it safely and just with my female roommates), that I study and work hard, and that I not have sex until I'm in a long-term committed/loving/respectful relationship (and if I eventually do, to use protection and be smart). These few rules are ridiculously important to him.

I have pretty much screwed up on the last one. I met a guy here and things ended up escalating very quickly. I did a lot of things with him including some things that are on video (that are especially incriminating without context - I feel bad about this part most of all).

I also stupidly told him how bad it would be if my father found out about those things and now the guy is using it against me. It started out jokingly but it's now clear to me he would make sure my father found out these things if I stopped having sex with him.

I don't know what to do. I feel so stupid and completely to blame for all this, but I only chose this school thinking I would be able to go to it without accruing a massive amount of debt (which is in my name - my father has only agreed to pay based on me following his few rules and I am now a sophomore and all the debt is in my name). 

He asks for so little and I screwed up big time and am now screwing up even more to cover it up. A part of me feels like I deserve all this and I feel terrible for worrying so much about the money and not simply disappointing my father but the fact is the debt is so staggeringly large I can't think about anything else.

Can you give me the gist of the text in a nutshell?
<bot>: my father is paying for my schooling based on me following a few rules, I broke the worst one and am now being pretty much blackmailed for it.
