How do i tell my boyfriend to stop being a trouble maker

I have first hand experience with this. You need to tell him that it makes you uncomfortable and that it needs to stop for the relationship to continue. If he loves you, he should at least make a noticeable change. But sometimes they will do what they want to do, no matter what anyone says and if that happens, they are not going to change until they have a wake up call.

Let him know you are concerned and if it's effecting your relationship let him know. If he loves you then he will consider your feelings.

Talk to him at a time when neither of you are likely to go anywhere and really explain how it makes you feel. If you think it's gonna affect your relationship it's important that you talk about it with him. If he cares about you he'll definitely understand.
