Because they're insecure.
The lead vocals guy was having an affair with the drummer's girlfriend
(if your a guy) The girl your having an affair with must be aware of the fact that you already have a girlfriend. If niether girl knows about each other you will get busted.
hEY MEANS dump her!!! SHE is having a affair with another guy or doen'st love you anymore
The dream expresses your own emotions. It does not provide any information about the guy's thoughts or feelings, or those of his girlfriend.
maybe they say is she having a affair with a guy named david hill
The dream probably expresses your jealousy or feeling of being inadequate to hold the girlfriend's interest.
She has an affair with Quagmire... "Giggidy Goo"
It depends. If you think your girlfriend could be having an affair with another guy, you should be completely honest with her and ask her straight out what's going on. Rather than go yelling at the other guy, go straighten things out before jumping to conclusions and getting yourself in a huge mess.
This only means that the guy probably is someone the dreamer sees regularly. The dream expresses the dreamer's jealousy and lack of trust. It reveals no reliable information about the girlfriend or the other guy.
you just say yes
Dreams are about the dreamer. This dream represents the emotions and perhaps the desires of the dreamer. It provides no information about the guy's emotions or faithfulness.
It depends on where you meet them
