STUPID boyfriend, betrayal . feel like a dumb ***. i need some advice please........................…

Sounds like a really bad thing going on there.. i'm sure you probably love him a lot.. but if he is doing that and taking their side and not trying to be with you and make things right then maybe he's not the 'right' guy for you. You don't wanna be in that kind of relationship because you want them to care about you more than anything and choose you before anything else. If he is being like that maybe you should just move on and find someone better that isn't gonna be making your life so miserable. I really hope that this helped you. Lot's of luck for you
