i guess she doesn't want to be plagued with my apostate disaese.
Your wife must want to become intimate with you again on her own rather than because she was pressured, guilted or talked into it.
It could be something else, but you likely are right about her being resentful about you no longer wanting to be a JW. Remember, she's got a whole head full of JW induced fears, notions and anxieties about marriage, marital roles, sex, life, death and big picture issues, rattling around in her head. You calling it quits as a JW is likely bringing them all to the forefront and nothing makes one feel less sexy or less like having sex, than fear, anxiety or resentment.
I'm guessing that by all you've said to her on the matter, she knows that even though you don't want to be a JW, you are willing to do whatever it takes to support her if that's what she wants and are anxious to get things back on track with your marriage. I've been married the same length of time as you have and here's what I'd do.
1. Unless she brings it up, I'd stop talking about wanting sex, he's well aware that you do. No one wants someone forcing food on them or inviting them to eat when they aren't hungry. It's the same with sex, if you aint' feelin' it....you aint' feelin' it. Forcing the issue makes it even worse.
2. I would stop talking about anything JW related unless she brings it up and I'd let her do most of the talking, only asking the occasional question in hopes she will see the nonsense in the patented JW answers she gives. Don't point out the flaws in her answers, just listen and consider what she's said.
3. I'd find subtle Tailor made ways to help revive her affection for you. I wouldn't do this because you want it to lead to sex, rather do so because you first and foremost, really do want her to feel "that way" about you once again and you want to make sure she knows you still feel "that way" about her too
As and example, here are a few of the simple things that I do that seem to go a long way with my wife. They are not intended to trick her into anything (sex). It's more a matter of reminding her that I know her better than anyone else and that I do pay attention to her and she matters. ( plus it's kinda' fun)
When my wife is a vulnerable position such as standing at the kitchen sink with her hands in soapy water, I come up behind her and softly kiss the nape of her neck just below her ear. Depending upon her reaction, I may smile and leave it at that and go on about my business or I may go one step further by pressing in a little, reaching around and grazing my fingertips along the front of her thighs and nibble on her ear. Usually I feel her knees falter or her breath quicken a bit and I know I'm on the right track. I give her a soft pat, gather her hair up and whisper in her ear, then become busy with something else and leaving her smouldering.
Throughout the day or even several days, I look for more opportunities to catch her in a position where she isn't able to respond to what I'm doing. Sometimes in a store or somewhere public with other people around, I absentmindedly let my hand slip off her shoulder and lightly graze the side of her breast or along the back of her arm. Without being obvious, I notice her reaction and if it's favorable, I may slide my hand slowly down her back letting my fingernails graze as they continue a little lower than they should in a public place. If she looks pleased but a little embarrassed, I know I'm on the right track but musn't go too far.
If we pass a jewelry or perfume counter for example, and something catches my eye I'll stop and walk backwards a few steps, pulling her with me and ask her what she thinks of it. Usually she likes what I've spotted but often sees something else even nicer. I pull her over to the mirror and look at her admiringly as she tries it on. Even if she only want's to look, rather than buy, she seems pleased that I am interested in things she likes (and I really am).
One thing she likes is for me to read aloud to her in bed. Sometimes if I happen upon something I know she'll like, I tell her about it . Expecting nothing in return, I encourage her to come get ready for bed early and I'll read it to her.
Usually on the weekends she makes a full on breakfast. Sometimes I put some music on and if I hear a song I know she likes, I slide the frying pan off the burner, spin her around and we slow dance around the kitchen. She laughingly protests that "breakfast will be ruined", but I know she's pleased. She must be well aware of what I'm up to after all these years, but I've never talked this to her about it. I know that doing so would ruin it.
What I'm trying to say is that I think your wife needs to be reminded that your marriage isn't defined by your being, or not being a Jehovah's Witness. Your consideration of her feelings by not saying anything negative about something she holds in high regard (JW's) , coupled with your genuine interest in her as a unique individual, will go far in rekindling the warmth in your relationship . Now that lack of sex has become an issue, you need to take the spotlight off sex itself, by looking for (genuine & honest) ways to make that nice part of your life together,overshadow the JW part that has become such an intrusion. Don't do it because you expect anything in return, rather because you enjoy making her happy.
