One Change Leads to Another...

So, something that I have noticed about people, especially on campus lately, that when people change their relationship status something else changes too. It has just been getting on my nerves that when some people get in a relationship they think that it fixes all of their problems. Since they think that they feel like they need to spend almost every free moment with that person. This just really upsets me, especially when college is supposed to be the time where you build friendships. I just do not realize why people do this. If anyone has any understanding of this I would appreciate it.
