doing lines ?

i️ read through my boyfriends text while he was asleep i️ do it rarely to check up on him. today he had came home early for lunch because he said he knew work was gonna be busy so he wanted to take an early lunch. i️ read his messages and he was texting a close friend about clocking out so he could go smoke with him, i️ have nothing against my boyfriend smoking weed but he asked his friend, “are we smoking or doing lines?” i️ have no idea what to think or do. we have a 3 month old son... i️ need advice 🤧
