My friend is trying to break up me and my boyfriend do you stay friends?

Dude totally no. if he/she changes give her aonther chance but i wouldn't be her friend. it depends on how long you've been friends. 1 day through 5 weeks is a no go. a month through 6 months maybe. 6 months through a year 50/50 a year or more give her another chance. hope i helped!
same thing is happening to me he or she can't be trusted don't be there friend and than let them chance after you when they realize what they have done
