I'll try keep this short.
I'm a 22 year old graduate at one of the biggest banks in the world. I would say that I'm good looking, I work out a lot and I'm pretty lean and stuff. I've never really had a problem with girls, but I'm not the type to play around the field, I'll only enter in with someone I care about. Met my senior managers daughter at a BBQ just after I joined (she's 31). Anyway she seemed like a nice girl and we became friends. Then one day her dad pulls me aside and essentially threatens me that I HAVE to go out with his daughter (as in make her happy, date and stuff) or he'll make my life a living hell (he said it in a sly way that can be interpreted in many different ways, but made it explicitly clear in that moment that he was serious. Sure enough she asked me out and I said yes as a result of this. She's actually very annoying, really clingy, always wanting to interfere in my business (went to go spend a week off I had with my family and she got pissed at me? Wtf). I really don't like her at all, but I'm too scared of what the senior manager said, and I can't imagine he'd be too thrilled with me if I dumped his precious daughter. She's fit but I don't want anything to do with her. This "relationship" has been going on for about 6 weeks now and I can't take any more of it. How do I get out of this mess?
