<human>: Can you provide a brief rundown of the text in within 3 sentences?

I [21 F] want to take a trip with my boyfriend [21 M] but I don't know how to bring it up to my mother [56 F]. I live at home and my parents pay for my college expenses. 

My boyfriend and I have been together since April 2012, almost two years. Our spring breaks happen to line up at the end of February. We wanted to take a trip to Chicago. We live in Detroit, so it's only a 4-5 hour drive.

My mom is a little more conservative than I am. I know she won't like the idea of my boyfriend and I in a hotel room together. Honestly if I was away at college, she would have no idea what was happening in my life. I really want to take this trip with him, but I don't want to mess with my free college, housing, and the car they let me use.

Do I ask my mom to go? Or do I just tell her am I going because I am 21 years old? How do I approach my mom about going?
