Why do people assume that people only have affairs for sex?

In my (our) case sex wasn't the driving force. Sharing a simple day in the countryside or a long chat over a glass of wine and yes the occasional intimacy was what we both enjoyed. The whole being together and enjoying each other's company was what made it special.

I 'like' but don't 'love' him therefore I wouldn't ask him to leave his wife nor would I let him tell her about me (even though he wanted to). I hope this makes sense?

How many people choose to ignore or even actively encourage their partners to have an affair?

I've heard of those who simply enjoy the status of being married (or coupledom) and all the benefits it brings. They don't want to rock the boat or overturn the cosy applecart.

This is fine for the husband and wife but what about the poor lover?

Please note: I don't intend continuing a relationship with MrX (or embarking on one with MrY or MrZ) if they're in a "permanent" relationship with MrsX (or MrsY or MrsZ)!
