Being in a relationship can be tough. There's a lot of ups and downs that go on throughout this time, but overall it should be on of the best times you'll have. There's always something you'll disagree on. You'll want to sleep alone, but you know you can't because you spend so much time together it's impossible to do it. A date is going to the dinning hall most of the time because no one has a car or money to go off campus.
You skip the living separately part because you see each other so much, you might as well be married. Although it is just freshmen year, you hope that it lasts forever because you couldn't imagine anything else. He'll be that one person that helps you through your most stressful times, and you'll be the person who gets him to do his homework. He'll be apart of helping you succeed and you'll be the same to him.
His roommate will be a crucial part of your relationship because he's the one who lets you stay the night and doesn't care what you do. He's the one with the car that helps you get around and stock up supplies for the room and daily Walmart trips. He's the guy God sent down to let both of you be happy.
At the end of the day, you both can't get enough of each other and you both (including the roommate) get stronger together.
