When Toby's wife left him, it kind of put him in a dark place. There's a few moderately subtle references to suicide in Undertale, and the reason Toriel and Asgore don't get back together- and the reason Asriel gives you an "I just can't, OK?" in a saccharine ending about saving people through the power of friendship- is clearly because Toby had a touch of depression.
