Jordan, HELP!

I'm 20 years old, have been dating this guy for 4 years. Sat down to check my email on his computer last night and I found a google search page for plus-sized lingerie! My feelings were instantly hurt, I felt so ugly! My boyfriend has never called me fat or anything, but just the fact that he looked up plus-sized lingerie means he thinks it, right? So what now? Am I just overreacting? My feelings are SO hurt!

(By the way, I attached a picture of me along with the two 'models' he was looking at.)
