You said nothing was said. Anything else happen. A little kissing, hugging?
What would Jesus do? Well, what did He tell the adulterous woman at the well?
I understand what the elderly lady at church meant, but this is a WW! Jesus was never manipulated by anyone. If you can do what He did and not be manipulated, great. A WW will try everything to temp check you, including sex! Now, you can ask yourself WWJD all day long, and I guarantee you will find an answer to fit how you want to fit. B/c you are too emotional, needy, and human.
No, I am not saying you should have kicked her out! If you did nothing, then I think you handled it right. I think she'll do it again, so don't be caught off guard. If she starts kissing, you may need to ask her what she calls herself doing (or something similar). You will want to have sex, of course, but I think it would be a mistake. Don't be mean or "kick her out" by trying to see how rude or cold you can be to her. You don't have to be hateful. But I think she should see that you are not easily manipulated by her emotional swings. What would she think, say, or do if you went to her bed and spooned with her......? Somehow, women seem to think it is unacceptable for the man.....but it's okay if she decides to do the same thing. That's b/c she calls the shots when it comes to sex, and she will use sex, if needed.
You see, nothing would suit a WW better than to be able to give the H a little spooning in bed, and that would be all he required to get back into the MR. It is going to take a heck of a lot more than a little affection to fix this problem. She needs to know that you aren't that easy. Sure, she'll be mad, if you tell her. You can decide if you want one night of sex and rejection afterwards, or stay strong and her do the work to get the healing?
It is not about what you feel should work in your M. It is about doing the work that gets the right results. Do what works!
