so my boyfriend, my bestfriend, and i were a classmate in the senior year of highschool. but they're not 'that' close to each other, just a normal friend.

now they're going to the same college while i went to different college which made me met my boyfriend rarely.

so there were 3boys and this 1girl. that 3boys including my bf. and now I'm feel like they're getting close. the girl sometimes even sleep over at the boys boarding house but in different room but my bf never told me that. and when i talk with her about my bf i feel like now she knows my bf better than i did. cause how can i know about him if he never tell me anything about his college life. he never mentioned even one of his friends in the college.

if you were me, what would u feel and what would u do?
