TITLE: Me[19F] with my [19M] bf have been together for 1 yr, uneasy about him rekindling a friendship with his first same sex love.
POST: Me and my bf have been together for just over a year. Both open about being bisexual. He has in the past 'cheated' on me via skype sex. So I am still trying to trust him as much as I can. He and his best friend in high school apparently proclaimed their love for each other and decided not to act on it  but fell out of touch when the best friend got a gf. Now that best friend has broken up with his girlfriend they are starting to talk more and it is making me feel uneasy? Am I being silly? I am really unsure whether I am overreacting so haven't brought it up with him.
TL;DR: 
Bf's first love was his highschool best friend, they have recently started to talk again which makes me feel uneasy.
