Short temper bf

I really need to talk to my bf about some stuff that bothers me, but the thing is he can kinda explode sometimes and talking to him isn't easy especially about stuff like this...I need tell him that I don't want him to talk to this one girl and losing all contact (because of reasons  in the past) and I really don't like how his friends are with me and I need to confront him about him lying about some stuff... I don't want to lose or leave him but we HAVE to talk about it... Some ideas on how I can do this ?
