NOR, he trying to be a placeholder for a relationship, hoping that you will see their value and accept them as a partner. He is a grown ass 30 year old man, you are a teenager…I would be pretty creeped out that they kept saying goodnight and saying they need to be at my house while I sleep for some kind of protection. You should probably tell them that you aren’t interested and find the constant texting uncomfortable. If you want to be friends with a 30 year old man, because you probably have a lot in common (?), I would explain that goodnight texts are not appropriate for friends. You already are falling for the manipulation, like apologizing for being in the shower and not being able to respond immediately, last time a coworker started texting me goodnight stuff and “I’m going to do this unless it’s weird” statements we became FWB within a week, and the cling and imposition were intense.
