you made a vow to her until death do you part.
Maybe this is the crux of the question. What IS a vow? I’m not trying to be pedantic, but take an example:
If I say I will stand by your front door every day for the rest of my life, and you say, “Wow, that’s great!” And so it is. But, at some future point you no longer value my role in so standing there. What value do I bring to maintaining my commitment, my vow? Maybe you’re indifferent about it? Maybe you originally agreed to offer me food in exchange and stopped doing so. I can still hold my vow, but to what end?
In my case, my wife is indifferent about my involvement in her life. If asked, she’d say she loves me dearly and respects me, but is committed to following Jesus and reading the Bible (I’m not suggesting she’s doing so with rational thought). And, to the extent her vow included doing anything more than remaining reclusive and alone, I suppose she broke her vow. Nonetheless, I honor the sacrament of our marriage. I forgive her, as I deeply believe she’s ill. What other mother could go years with no contact with her children? It seems that my best way to love her is loving our children. The vow to love and support her can be accomplished if we remain married, divorced, receive a decree of nulity, or if she dies, by managing her estate/affairs/love for the children and continued engagement with her family. I’m just unclear how doing all the rest of life alone supports that approach or how the love of a woman would inhibit my ability to support her and the children (perhaps even more!).
There’s no specific urgency, but my kids would benefit, I think, by having a woman’s fingerprints on their lives. While that could be by way of a paid role like a nanny, it seems that someone who loves and supports me might have the capacity to love the children more freely.
