It’s confusing why it’s such a big leap.
Because saying "I'll do [thing] until I die" is not the same as "If I stop doing [thing] you can kill me".
Also it’s odd to assume you’d break the vow after not accepting them cheating. From my cultural POV when you cheat. You’d forfeit the vow.
If the vow is broken by cheating, then the part of the vow about being lawfully wedded until death is also broken. So then you'd also lose your right to murder them to get out of the vow, since you're already out of the vow. If you'd like a fun take on divorce as murder, see The Orville's Moclans.
Which would bring dishonour upon your family and that includes a direct disrespect of the other family.
Is your culture Klingon? Because honour is not a real thing, it's just an excuse to shame people for doing things some don't like. If you've got a good reason why it has to be this way, I'd love to hear it. As it stands, that's just intolerance by peer pressure, which are both bad things to do. I'd encourage you to spend a bit of time doing some critical thinking about your culture, since I saw some of your other replies saying that some of your beliefs come from your culture. I come from a culture that still likes marriage a lot (Canada + Catholic), but that same culture is also responsible for (triggers incoming) genocide, child abuse, cultural cleansing, and rampant pollution.
Hey I cheated, or tried leaving (Not leaving because of abuse) since I believe if someone was abusing you. They’d also break the vow since the vow is to protect, love and care until death.
I'm not going to defend cheating too much, but the vow has no statement about monogamy (though that is usually and reasonably assumed to be the case) so the pedant in me would like to point out that cheating is not breaking the vow. Even with the reasonable assumption that cheating is breaking the vow, the vow does not set consequences for breaking it. Technically, divorce does not even break the vow. It is also possible to protect, love, and care until death while ending the marriage. Even after a divorce, your partner was still your lawfully wedded partner. (I don't really agree with this paragraph, but it's a totally valid opinion with some strong arguments so I wanted to mention it)
For Time do us part. While it may seem lesser. It’s acknowledging the flow of time and how someone can change throughout life. Though in reality there could be a better option but it’s more making it apparent the importance of meaningful statements.
I'd like to believe that the vow is acknowledgement that they intend to fulfill it until death. From that basic tenet and knowing that humans aren't perfect [citation needed], it's easy to come to the premise that somebody might grow to realize they can't fulfill that vow, and so they want to get a divorce. It's actually probably the most protective, loving, and caring thing a partner could do -- realize they aren't good with their partner and so leave. The fact that they broke the vow does not invalidate their intent to fulfill it when they started the marriage. This is basically the idea behind no-fault divorce, btw.
If you want to acknowledge time by changing the vow from "death" to "time", you're definitely allowed to for your own wedding. But don't presume that people don't understand the meaning of what they're saying because they made a vow that they ultimately didn't keep.
Here's a parting thought: Would a good partner ever murder their spouse? Is human life truly valued lower than this made up concept called "honour"?
While light bulb sockets don't change much from region to region, they definitely aren't all the same. For the bulbs (not the bars), there's two large categories: Edison screws and bi-pin. Edison screws also come in a lot of sizes. When compact fluorescents were rolling out, they got a new bi-pin connector from the USA: GU24. My whole home has GU24 fixtures (not by my own choice), but my lamps are Edison screws.
