Whats up with my friends? how do i deal with this?

Sounds like your younger. A 3 month? anniversary? That i can see why your friend was like ok. relationships come and go as your younger.. Its really not like the old days where you met some one in highschool and got married later.. lol.. Not even close.. I would stress less about your BF and friend situation and focus on school and more important things in life.. Later you will meet mature people who know how to act appropriate and not like fools.. Keep your head up!
