So today, when i had gone to meet my boyfriend at his workplace, we had a conversation about cleavage and his friend there, was like what is wrong with women wearing whatever they want to and suddenly he jumped onto her, and start undoing her buttons in front of me. Well i think he did not touch her but, that felt very uncomfortable and i really want to tell him that. I want to strongly say that i will never again resist myself standing there watching any of these crap.
How do i ask this to him/say this to him in a decent yet mature way. I want to handle this without any drama.
