One the one hand you say you can't live without her but on the other hand deep down you want to stray as is normal. The only thing to be concerned with is that either you worry you can't always control yourself and worry you'll screw up the best thing you ever had, or you are with this girl for the wrong reasons and she's not actually the right one for you, but you just NEED her at this time.

Just guessing but I only wanted to stray when I actually wasn't happy deep down. With the right woman you really don't think about it seriously at all and dreams about it aren't bothersome, just natural.

Attraction or need don't equal the same thing as it actually being "right".
