Hello there Reddit,  
I am a twenty year old college student, currently studying abroad with a few other students from my school. One of those students (we'll call her "L") has been a good friend of mine for several months, and is truly an amazing person. Over the last couple of weeks however, her behavior towards me has changed, and several different people have pointed out that she seems to have developed feelings for me. Usually this situation would be met with a "fuck yeah!", but there are a couple issues that are mudding the water for me.  
The largest of these is the fact that I am headed towards a relationship with another girl ("g"), who just so happens to have been the absolute girl of my dreams since arriving at school.  
The other issue is that my family is absolutely obsessed with L. My dad regularly informs me of how stupid it would be to pass a girl like her up, and my brother is convinced I should marry her.  
So what should I do? Which girl should I go with? And if the answer to that is G, then how do I avoid hurting L?
<bot>: I have the option of a relationship with two girls, one of which is my absolute dream girl, the other is one of my very close friends. Family is telling me that the latter is the perfect catch. What to do?
