<human>: Summarize the given text in a few sentences.

My first post - sorry if I've posted in the wrong section - it kind of straddles relationships, personal problems etc.

Okay, so my boyfriend has started smoking again (but "only socially") which I absolutely hate its sometimes a cause of contention. Remember this fact.

Anyway, one night I meet up with bf and his colleagues for a night out, its the first time I have met some of them, in particular this guy "Salim". I have been made aware prior to us meeting that Salim slept with my bf's other colleague. I turn up and I am talking to some people and Salim sidles on in is very keen to meet the "new person". I am introduced as bf's "Mrs".

Night continues and at some point Salim sits next to me and tells me how great my bf is, how he is one to watch, and not many people get promoted so soon yadda yadda - really bigging him up.

Later on in the bar he sits opposite me and is telling me about his relationship problems (i make the connection that he cheated on his gf with my bf's colleague - he doesn't know i know that - i make an internal note that he's a douche) - all the while my bf is part of the conversation but Salim is only looking at me and talking at me. Bf aware of this and commented on it later)

Then after a while he gets up to leave. Gives me a hug, shakes bf's hand, and bends over and says audibly to both myself and bf "he's a great guy, smokes a lot though" and just walks off and goes home.

Bf looks confused. I am annoyed at bf who told me doesn't smoke often. Realise that Salim may want us to have an argument. Baffled as to what that was all about...

He obviously knew that that was a sensitive subject so why would he throw a grenade and not even stop to watch it go off?
<bot>: Boyfriend's male colleague deliberately tried to cause us to have an argument, and I don't know what his motive was.
