Theories on why Asgore and Toriel Separated?

[Spartan Delta 27]

I really have no Theories of mine own to present on the matter, but I am curious as to what others may have come up with.

The Catalyst for this in UNDERTALE from what I remember is that Asgore made the decision to start capturing Human Souls (Hunting/Killing Humans in the process), which is a fair enough reason to cease all association with the Guy in Toriel's case.

As for "deltarune", I am not entirely sure why they would have broken up. Unless Asgore was going on another murder Crusade, it seems like there had to be another reason/reasons for it. The Townfolk are likely not going to give any straight answers, since the topic is awkward and Kris might already have a good idea as to why they divorced.

Something happened to Noelle’s sister, Dess. Asgore was police chief and failed to save her, and was removed from the force.

It's pretty obvious that the incident has to do with Asgore being removed from police chief (you can see this in ch2 epilogue)
That's all we know for sure, anything else are just theories at this point.

To be fair Dess’s implied disappearance is the only tragic event in the town that we know about, and the victim being someone very close to Asgore and his family would explain why it would have such a massive impact on the Dreemurr’s personally.

Asgore is also kinda useless

Conflict of duty and emotion. A policeman's duty led Asgore to commit an act that was condemned by Toriel and caused their relationship to break down. We know what happened in Undertale and the author left some ambiguous hints in the form of different colored flowers in the house of Asgor. Perhaps there are some violent laws regarding people in Hometown that we do not yet know. Asgore could not bear the emotional burden, or he had to make an exception for Kris against the law at some point, which forced him to leave his post.
Looks like Asgore is trying to do penance in some way by showering everyone with flowers.
Оne more worth noting thing. A suspicious bouquet of flowers under a glass cover, (reminiscent of what we saw in the house of Asgore) is near Rudolph, who is (presumably) on the verge of death. The bouquet itself is nothing special, but the glass cover adds some unsettling symbolism.

Asgore preventing Kris from getting Criminal Charges at some point is very believable given both Characters in question. If such actions were ever discovered, he probably would have been Discharged from the Police Force and pretty much looked incompetent... Also, if he were not at the Police Station during a very serious situation due to personal reasons (Such as responding to something Kris had done), that could easily result in the same. Sounds very reasonable (And depressing, but such is Toby Fox's Work). Sounds very reasonable.

Failing to save Dess as you mentioned earlier could have been such a traumatic experience that Asgore resigned from the Force or was dismissed after failing a Psyche Evaluation. Your point about Dess, Noelle and their Family being close Family Friends would definitely put a severe strain on the Household just like any Family Death would (I feel like I have seen this before...). Anyhow, I think this is a pretty solid idea too.

There is also some variation of this.
I made some mistake writing "laws against people", meaning "laws against humans". It seems that the monsters in Hometown don't really realize that Kris is a human and consider them just as a monster resembling a human. Honestly we can't even say for sure who Kris really is. So the conflict with the duty came when he had to hide the fact that Kris is a human. The way Asgor had to deal with other humans was the reason of ending relationship with Toriel.

hmm nice but i never saw dialogue saying that. perhaps its the hospital ch2 dialogue that i missed.

I get the feeling that the reason they separated won't be particularly harsh, since Toriel acts respectfully enough towards him in the shop in Chapter 2. If he'd done something truly terrible, I feel that even he would realise some flowers wouldn't patch things up between them.

My guess is that whatever happened, it likely was something that was something that specifically affected Toriel and caught the attention of the mayor as it seems like most people in town still think positively of him, which doesn’t seem like it would be the case if he had done something particularly egregious

It’s also possible that both events are somewhat independent - Toriel could’ve just felt like they weren’t compatible and broke things off, then Asgore’s performance could’ve fallen off as a result to the point where he had to be removed from his position

I could see that happening. For someone who uses Fire Magic, Toriel can be stone cold.

All that I do know in that regard is when she breaks up with Asgore (In UNDERTALE or "deltarune"), she really starts hating him with a burning passion. I never quite got that... But I will say that made me lose a lot of respect for her in both Games.

For those who might say she seems to be a lot less hostile to him this time, I recently completed Chapter 1's Epilogue and she HATED that I brought her a Bouquet of Flowers from Asgore. Whatever her issue is, she clearly despises even being reminded of him.
