Search Results: interested in a married man

I have a new job and a few days ago some partners (2 men and 2 women, let's call one of the men John) found out that I'm single and that I have no intention of marrying ever. Since then, they've been joking and saying that they're going to look for a boyfriend for me.

Today they said that John was going to take me to the dark side. I didn't really understand that but I thought they meant that he was going to get me a boyfriend and I answerd "sure", but it was obvious for my tone that I meant "no way". John said something like: "Yes, I am". And then one of the women said: "he would, if he wasn't married".

They kept on joking but John talked less than usually.

Now my question is: what did they mean by taking me to the dark side? Do you think that he may have some kind of interest in me? Maybe he finds me attractive or pretty and said something to the other ones and they were trying to tease him?
I don't know what to think but I don't want my partners to think that any of them have some kind of opportunity with me, they already know that I don't want to get married but they may think that they could get a one-night stand with me and I don't want them to think anything like that.

Don't answer if you don't believe in zodiac!

I am in love with scorpio man and he's a typical Scorpio.

Scorpios don’t cheat. They really don’t. They take love and marriage very seriously. Cheating doesn’t make sense to them. The only downfall with Scorpios, they can fall in love like 10 times in a month. It’s difficult to keep a Scorpio interested for a long period of time, but if you two are married, you’re safe.
