Idk what to do. bf lied and hiding things from me?

First of sweetie, guys are dogs! Especially at that age. He is in that adventurous stage. As for him not wanting you around his friends he is probably afraid that they will slip and say something about some other girl etc. And the whole tux thing.. he is lying through his teeth! He took some other girl and doesnt want you to know about it but face it sweetie you need to ditch him. And besides ur in high school and in just practice/fun relationships at that age dont last.......
