hopeless romantic society discussion

Ok I’m back. So my problem is i have a character b who deeply loves another character a and views them as their savior however character a kills character b’s not only best friend but found family member I’m currently struggling on how character b should feel yes they feel hurt, betrayed and all that other stuff but they also love character a so very much this person was their one beam of light was their only light in the darkness. So how should character b feel? (This is mainly to see peoples opinions and broaden my insight)

Omg I totally understand the struggle!
In this case what was character a's motivation to kill character b's best friend and found family? Maybe you could use that in the reasoning for character b to be a little less devastated. I still feel that character a would need to do quite a bit to be accepted by character b again. Mostly because character b must feel really betrayed and seeing character a while knowing what they did is not fun for character b. (I don't think it should be easy for character a.)
Now for character a being the light in the darkness for character b. To be honest this can still be there in a corner tucked away. It doesn't need to be gone. As long as it's not easy for character a to come back in. It can't hurt to make character b despise character a.
Also if character b trusted charater a alot or quite a bit. This would most definetly be gone. Maybe character b even fears character a. They might think character a was planning to murder them too??
That's kind of what i'd think the change in dynamic would be. I hope it anwsers you question. :)
