I find this behavior very hypocritical and insulting. Now she is all over me. She’s gone from LDW to HDW!!! However, I am emotionally in a different place! I have no desire to even try at this point in time and I think that the behavior is not genuine.
Have you said exactly this to your W? Have you discussed with her, what she plans on doing to ensure it doesnt happen again? Distrusting her behaviour, is not a bad idea. You have every right to question her motivations.
You can have sex with her and maintain your observation of her continued actions. If you start having sex, and notice that she becomes disinterested again, you can determine if it was sincerely wanting to meet your needs, or just reeling you in, you can have sex with her and maintain your boundary. I wouldnt normally say this to a HDM with a LDW, but You MUST talk about it. Going 20 years without doesnt really impress upon your W the importance of this.
She did not kill it. You allowed it to be unattended to. Your sexual needs are yours and yours alone to be responsible for.
