@Plinco , I think you identified the root cause of the problem in your OP. You said that she is boring to talk to. That in and of itself is sufficient to kill sexual desire.
I’m concerned that you might be jumping from the frying pan to the fire if you divorce her. You yourself accurately defined most modern women out there…”I see arrogance, jadedness, and ugliness.”
This sounds like a good girl except for the boredom/sexuality thing.
Is it possible to get her to explore some outside interests? I’m wondering if she was more involved with life outside of marriage, she might become more interesting. What if you both agreed to an individual outside pursuit and you can both discuss what you’re doing and learning? Maybe classes of some kind?
What about attempting some role-playing in the bedroom? Is it too late to try that?
There is a lot more to marriage than sex, although sex is important. I’d just hate to see you divorce and then on the other side realize you had it better than you thought. Most women today are trash. This girl is not. The fact is that most non-trash girls lean a little toward the boring side.
Sometimes we want our wives to provide intellectual stimulation that they are incapable of providing. I have struggled with that all my life with girlfriends. My wife is gorgeous and kind and submissive, but it would be folly for me to expect the same intellectual stimulation from her that I get from men. They just aren’t wired for that.
I have learned to accept women as unable to provide the whole package. For intellectual stimulation, it’s men all the way. Women by nature are intellectually boring AF, and will always disappoint in that area of life.
If you found a way to stick it out with her, as the years go by you might find that the differences you see now will diminish in importance.
I totally get how you feel. I’m just tossing out some thoughts for consideration. Just consider slowly and methodically fixing the issues before resorting to rummaging around back in the trash heap.
