Have you ever had a romantic relationship with someone who was also having a romantic relationship with someone else?

No, but I have had a romantic relationship with someone while I was having a romantic relationship with someone else.

No, but I've thought about it. And didn't, because that wouldn't be fair to the other person.
There wasn't an option for that.

Yes, but I didn't know that he was already in a relationship.

I had affairs when I was married with people who were also in marriage relationships. It was all out in the open though..their partners knew and approved.

I had relations with a man I didn't know at the time was married. I have also had a relationship with a man who had a romantic relationship with another woman. I knew about her, she didn't know about me.

Wow! My survey isn't dive bombing! ...amazing.

It's a good survey

(tears in eyes) "Thank you! ::sniffle::: Thank you all!"
The results are pleasing too. Just what I needed to know.

yes, and i knew about it. actually the other person was seeing multiple people, we both knew and it was ok.

we like you, we really do like you!

Aw, you're just sayin' that!

I was living with a gal who was carrying on several extra-curricular relationships with out me knowing about it. When I asked her to marry me then she confessed her sins. No, I didn't marry her.

This kinda stuff really pisses me off. If somebody is devoted to someone, they shouldn't cheat on them

Definitely not something I can handle, either coming or going.

for a lot of people it's not cheating - they've discussed the boundaries of their relationship and by agreed that it's okay for one or both of them to see other people. In that case it's not cheating.

in that case my statement stiil holds true: cheating is wrong

yes and it didnt go too badly, i knew he was with other people and he know i was, as long as everyone is open about it then its fine

I started to date a woman and fall in love with her, she told me about her steady boyfriend, and my passion cooled off. Later she married him. It was sad; I think she might have been the one for me...

Yes, but she was leaving him, she didn't, so I left her and went to Cancun with my SCUBA instructor...
Although he was a guy, the single beds were appreciated!
(Clarification, he had always wanted to go but the cost for a single person was 30% higher, and that was more than he wanted to pay, the cost for a triple was reasonable, saved me 15%, but he didn't want to be a third wheel, or a third anything!)
