My bf doesnt get jealous

My bf does get jealous hell tell me to hang with dudes or i better not do this but if a dudes looks at my ass when my bf right there or tries to talk to me he doesnt say nothing. Just recently he had my phone and a guy inboxed me "when are we going to fuck" and he just gave my phone back to me i was looking for a reaction. My exa constantly hmu trying to get me back and still nothing i dont understand why he tells me something but not the guys is he being a punk or does he just knows ill  handle it myself correctly
