I was talking to a person for a while, sometimes we would go from 11 to 2 am(time difference). Whenever they left they would always be like "brb" and "gotta go eat and stuff". Its been a few weeks now, and we still talk, but for some reason they keep leaving me on delivered and shit now. No explanations, no "mb bro". Like, we used to talk in the mornings and be like "yo im back" and continue talking, but now they answer like a fucking snail sometimes. I know they're not busy either, because I can see their activity and i make sure to message when they have time, like the weekends or like during the night time. is this normal? i've never had this happen and always chatted with friends through games and other group chats and stuff so i don't really know. should i take the L and just talk to other friends?
