How do I get out of this situation?

[bold3in1]

How do I politely decline without being rude?

Some back story, I have worked with this colleague for a couple of nights, and we chat occasionally but just friendly chat. We had a work night ought the other week, and my 'best friend' at work sent me a message at 3am that she was sleeping with said colleague and he said I was attractive. I drunkenly replied, "Awh thanks! Tell him he is too".

I have been seeing a guy for the past 3 years.

Now I believe I have given him the wrong impression, but I am 90% that my friend/colleague would have told him that I had a boyfriend.

How do I respond to this?

"Work drinks sound great soon!"

Gosh forgot the vital part! The said guy from work messaged me asking if I'd like to go for a drink with him

What do you mean by your work colleague was sleeping with him? Do mean having sex or crashing at his house or sharing a hotel room?

Just don’t answer. Is the friend a Male ?

Are you drunk now?

You aren’t very clear at telling a story.

Just say no, and tell him it wouldn't be appropriate as you are in a long term relationship.

Gosh I know, that was an awful first post.

Basically a work colleague has asked me to go for a drink. I do not know if this is as a date or not. How do I say no without making it awkward, as he is senior to me.

Presumably he finds your friendore attractive

'Sorry if 'mate' gave you the wrong impression, I am in a long term relationship. There will be no drinks!'

What do you mean your friend was sleeping with him????

Just say 'thanks for the offer but I'll have to decline' that's it!

Maybe “cool I’ll chat to ‘best friend’ and find a time we can all go out”

Why not reply something like sounds good, who’s going?

Hang on a minute. Your friend was sleeping with a guy from work who told her he fancied you? And now he's asked you out?

Msybr he wants both of them

That's why I asked the OP to clarify. Either the guy is working his way through them (urgh) or he's genuinely interested in the OP alone.
