TITLE: My [F/19] bf [M/20] doesn't understand the importance of networking
POST: We've been dating for a year.
We're college students at a big university. It's hard to get one-on-one time with professors, let alone be recognized by them.

I invite him to come to clubs with me (academic clubs like Physics club or Geology club), and he usually politely declines. Then I'll go, and afterwards he usually says things like "I get really lonely when you go out", which makes me feel guilty about going out at all - whether to network or for fun. I don't think he's intentionally making me feel guilty but it's not a nice feeling either. 
What confuses me is that those are clubs related to his major, and are filled with interesting people. 
The one time I brought my bf along to an event, he stayed by the wall and ate the free food the entire time. He didn't try to interact with any of the professors or grad students that were there, although he at least enjoyed the food and said he was glad he came (But it seemed it was for the food, not the people).
TL;DR: 
What is my role as a girlfriend here? Should I drag him to events and introduce him to people, or do I continue inviting him and getting declined (except when there's free food to be had)?
