<human>: Give me the gist of the text in a nutshell

We'll be hitting our 2 year anniversary soon. 

I can't figure out whether she means something to me or not. When we are back home during breaks (both of us are in school), there is an about 1.5hr driving distance between us. Usually during breaks I have no desire or need to talk to or text her.

When she's in town and asks to hang out, it's a 50/50 whether I want to hang out with her or hang out with my guy friends - usually I oblige her because I feel guilty about not wanting to hang out with her when she's in town.

When we are together, it's a lot of fun. Her smile and laugh make me feel great and her bubbliness makes for a great time. I have no trouble talking to her at all and in general I have a great time with her.

In college we both are busy so I only really see her at night when she comes over to study/sleep and select nights when we get dinner/go out. Otherwise I have no desire to talk to or text her...

Can you guys gauge what's going on? I feel like after almost 2 years I shouldn't be so ambivalent with my feelings. Maybe I'm thinking too much about it.....
<bot>: I have no desire to talk to or text my girlfriend of almost 2 years when we are apart, but when I'm with her I have a lot of fun and enjoy her company. What does this mean??
