Bro

You are so right in saying thatIts like he's going insane from just what he seen and heard so far about her past lives and personally I wouldn't want a partner hurting that bad from my past or drowning in regret or wishing they were hurting instead of me. Doesn't feel very healthy as you said and kind of scary and sad reaction ngl...:/

No fr bc not only those he want to hurt instand of her but he literally said that he finished he killed himself before so that they don't meet and so she doesn't have to suffer. Like if you don't think deeply thats kinda sweet like he would do anything for her but when you actually think about what he is saying. He would kill himself or anyone else(the trash we have to call prince) just so that she is not in the pain even though I think she would still be

Actually* not finished i do not know how it turned at as finished

I think its the fact hes assuming what would be best for her without hearing from her first how she feels and what she prefers to happen. Hes literally just going crazy and i dont shame him for doing that i think anyone would be if they learned they had a second life and started remembering past memories and learning that you may be causing pain to someone but I feel like this may be solved if he'd just console her instead of assuming what she'd want or what's best for her instead of her saying it
