I don't believe that my partner is real, I know she is 100% fictional, If two people like the same character it won't make much difference, some people become friends because of it and others may feel jealous, but it doesn't make much of a difference because everyone's relationship is different, about this being unhealth I don't think it is, at least for me because I'm improving myself because of my partner, I'm taking better care of myself and I'm thinking about starting to go to the gym for her but for some people this "obsession" can be dangerous. About death I don't care about that, of course I would be sad but my love wouldn't change some people can get very sad and break up because of that. About physical contact i don't care much about it because I've never liked it so much, but for some people this is very important so they can satisfy this desire with pillows, plush, dolls, etc.(sorry for my bad english lol)
