Yeah I’m sorry but between not knowing where he lives and the fact he might go to rehab without telling you - that’s just weird to me. That’s a shocking lack of communication. Being ashamed of his home environment or his family, etc, is completely understandable. Not actually knowing his address or having any way to verify his condition with someone else who knows him is really weird. I hope he’s ok. If my bf was missing for more than 48 hours I’d be pounding on doors.
