Like I said, no man is ever going to say no.
Sorry, wrong answer. I'd turn down any woman who came on to me, no matter how attractive. I've spent 25 years building a relationship and I'm not about to throw it away.
You're just making an excuse. Males are responsible for their actions just like females are.
I would say it is dead. To have thoughts about other men is a good sign that her marriage is dead. If you truly love a person, you would never think about anyone else.
That's not necessarily true, either. Couples have private thoughts. My wife and I are completely dedicated to each other, yet we've both had moments of fantasy about other people.
But it ends there. Neither of us would consider acting on those moments of daydreaming.
The woman's marriage may be dead here. That's irrelevant, frankly. The relevant fact is that she has not yet seen fit to divorce her husband, and until she does so, she's sexually off limits.
If you're at a point where you're willing to act through cheating on your spouse, you should man up and end that relationship
BEFORE you do so. Not doing so is selfish and means that you want to hedge your bets - you want to get some outside action without having to give up the comfort and advantage of the relationship you're currently in. It's unfair to the other person to play both sides to your advantage.
It is possible (though uncommon) to have a successful "open marriage", but that is a completely separate thing. In an open marriage, both spouses are aware of the situation and agree to it beforehand,a nd have equal opportunity to have sex outside the marriage. That's totally different from cheating.
Sprite, tempting as it is, chalk it up to the lager, end it with her, and don't let it happen again.
