Another idea: when he asks you to dance, turn him down! Just make sure you don't accept another offer to dance during the same song.
I know guys like this. They think any action from you indicates you must be totally in love with them. You have to stop this slimeball in his tracks. The first step: DO NOT DANCE WITH HIM ANYMORE. Second, DO NOT ACCEPT ANY INVITATIONS TO HIS HOUSE. Even if the wife invites you, DO NOT ACCEPT. That is asking for trouble and telling this man that you are interested in him. I know these seemingly innocent actions on your part are just that--innocent. But creeps like him will misinterpret innocent actions as that of being interested in having an affair with them. Guys like him are only thinking with their D*CKS.
I would not stop going to the studio just because of this horndog, but again, you should stop dancing with the guy. And repeatedly dancing with this man is even worse. Right now this deludenoid thinks you are totally in love with him, even though you are not offering any encouragement. Just the fact that you keep on accepting his offer to dance is enough encouragement in his eyes. If you are forced to dance with him (like a Jack & Jill or snowball), and if he gets fresh, like the other poster says, firmly tell him he is married and that you are NOT interested.

Those who operate a studio may correct me if I'm wrong, but if you try the above techniques and it lacks the desired effect, you should also raise the issue with your instructor.

I teach ballroom for a Continuing Education program at the local U. It's part of my job to make the learning a good experience for all -- I discuss in class matters ranging from failed hygiene to roaming hands, and will take offenders aside for a private chat if need be. That would include someone behaving in the manner described. Repeated transgressions could wind up with the perp being barred from class, but it has never gone that far -- a word from the instructor is enough.

Again, I would urge you to try dealing with it yourself first -- but if that doesn't work....

There's nothing wrong with accepting an offer to dance the same song after turning someone down. It's not that she doesn't want to dance, she doesn't want to dance with him. Where the confusion about accepting another offer to dance comes in is when one has made an excuse. If you are too tired to dance with one you are too tired to dance that song, period.

Nobody should have to turn down a gentleperson just because he or she did not want to dance with a creep.

I agree with you, if she turns him down and than dances with someone else, it is good way of giving him the message, she is not interested in him.

I think it would be better though, to tell him straight out, she is not interested in him and she is there to dance with everyone, not primarily with him. He does not seem like the type to pick up hints and will probably require the direct approach.

How does the wife react to his behavior toward you?

Once at a wedding, I danced with a colleague's husband, who behaved very inappropriately toward me. Afterward, the wife started to be very friendly and kept inviting me to dinner. Fortunately, I figured out what was going on before I accepted: they were *both* interested--in a threesome!

You never know.

We have a weird situation at our studio aswel!

This guy sometimes comes to our class where I teach with some other teachers and he smells like he's really drunk and he 's just annoying and doesn't leave you alone! He tries to be your best friend or something!

How do you let someone know to leave you alone, you just can't kick someone out no matter how freaky or scarey they are!

People that are really weird can get into sensitive positions and have a tremendous impact on other people. (sorry for my english i am Greek)..
In answer to the question of why it happened, I offer the modest proposal that our Universe is simply one of those things which happen from time to time.
these things happen allways i believe !
the point of view is that u feel uncomfortable with the situation and better try to end it.
If the only tool you have is a hammer, you tend to see every problem as a nail.
just blow him off with a reasonable way that he could understand that u are not a kind of person he thinks .(Think funny) The best ideas come as jokes. Make your thinking as funny as possible.
(his wife might be a lesbian and her husband might want to hook u up)
he might want to make his wife jelous !
or he might be weird
or maybe maybe maybe !
leave it all ,feel nice and free ! let it go and when that situation comes again just smile and and say NO ! NO NO NO!
SIMPLE !!!
:)))

Only this-- you do NOT have to apologise for your english-- i am fairly confident, that it is better than most posters Greek !!

thank u very much !!!!
that was quite encouraging :))

Thanks for all your replies, I have tried talking to him reminding him he is married his reply was he is not a monk! He told me this is his second wife and an affair ended his first marriage - surprise, surprise! I made it clear I will only talk to him and dance with him but that is all. He did not get the hint, and kissed me on the lips at a dinner dance his wife was standing next to him, they are both weird. The teachers are fine with me they were all concerned. Im taking time off for now.
