What becomes of a DB wife?

So what actually happens to a DB wife when you break up? My wife doesn’t like sex anymore (enjoying sex for her was up until kids happened). She has disliked sex for years now and now complains that’s it’s painful because of menopause. I would just like to add here that it only happens a couple of times a year anyway and she would get annoyed if it lasted more than a couple of minutes. So now instead of 2 times per year (for 2 minutes max) it’s now down to zero. She is 50 and I’m 52. I love her still but need a sex life with someone who is into me and enjoys sex. I’ve been thinking a lot about breaking up and I wonder WTF would she do? We have kids by the way. If she dates a guy he is going to eventually want sex, but she hates sex and now complains it’s painful. So I guess I’m just curious what her life will be like - given we shared a couple of lovely kids.

UPDATE. Wow, seems to be a lot of people laying the blame with me. We used to have a great sex life, and I am a very attentive lover. Nothing has changed on my side, the change is all on her side. Her labido has decreased for years prior to menopause. The menopause now just seems to be another reason to not have sex. And for all the just use lube, and do more foreplay comments, you’re not understanding - she does not want to use lube or have foreplay, there is zero sex drive there now and she’s not bothered about it.
