Do you think your partner has already guessed that emotionally you're with someone else?

If you have to ask.....

You're making an incorrect assumption.  

Hmm depends on how good you are at hiding it :P

He may...yes

ive never had a partner so i dont have those issues

Alas, she may suspect that even if I am not. I had a girlfriend like that for a little while. Too much drama.

Emotionally I am with Donald Duck.

Shhhh.  My left hand is helping me type this and I don't want him to know.

No, I don't allow myself to get close to anyone like that to temp anything like that. 

He knows that will never happen. 

Nope, because I'm not with anyone else.

No because when things are going well I get comfortable and my emotions tend not to stray. Even though physically I might and often do stray which means I have to put brakes on my emotions which I am pretty accustomed to doing.  Years ago I began seeing the guy who lived above my boyfriend and fell for him so did feel that though I stayed with my boyfriend until he finally realized I was seeing someone else which was after a couple of months.  Which brought it all into the open and forced the breakup.  Then though I loved the guy upstairs it was a while before I committed myself to him because I felt I should be more independent.  Then once I did eventually I started seeing my former boyfriend because I missed sex with him though emotionally I was committed to the other guy.  What a tangled web. But mostly I wait until a relationship runs its course and has ended before I deal with the emotional fallout of breaking up.
