I know that my partner used to take drugs on a regular basis, such as on nights out, in his previous relationship. As far as I'm aware he hasn't while with me (2 years). I have never taken or bought drugs myself to know if I'm worrying that he's going to be buying/taking drugs for nothing as I know he struggled to stop taking them last time.
He has messages on his phone with a man where he has asked this man to "sort him a larl en out", the man says he only has 40s now and my partner says that will do because he won't manage all day just drinking because he hasn't been out drinking for a while.
Does this sound like he's buying drugs?
