Of couse it is; that's just wrong and cold. Cheating is by definiton having sex with someone who is not your partner.
No.
yesno it isn't but, it means you probably either like him already or he is just one of your friends you had in your head as you went to sleep.
If you are in a relationship or seeing someone, I would say definitely not. If you both agree that you would like to be friends with benefits no problem. But make sure both of you are on the same page, This can be a little tricky if one of you has not moved on.
You can't, that would be cheating.
of course dump him NOW!!!!
Are you looney? Why would you want your girlfriend to sleep with anyone?!
He may still be trying to sleep with you for only him... he may like to sleep with you.. or maybe he likes you and his new girlfriend..
Are you keeping this a secret? Would your partner be hurt by this news? Would you feel ashamed if your friends and family knew about this? If the answer to these is YES, then YES it's cheating.
yes shes probably cheating on you
Either by myself or with my girlfriend. ;]
It probably means that you are worried that your girlfriend is going to cheat on you with her ex. If you are thinking of something, your subconscious mind might be thinking it. Although nobody knows for sure why dreams occur, it probably has something to do with your subconscious mind. So try not to think of it at night. Chances are what's on your mind when you go to sleep is what you'll dream about. Or you may need to get something off your chest. Try telling your friends, your family, your girlfriend, even a psychiatrist about it. But I bet if you are a good boyfriend and your girlfriend is loyal to you, you don't need to worry. Hope this helps and good luck!
In your place I'd ask myself why she wants or needs to do so. Every home has a couch.
