I suppose though your wider point is what is love? I mean is it a feeling. A behaviour. Both of those things. I guess when I say I'll always love someone what I mean is I'll always carry that person in my heart. Always feel love for them.
I suppose the truth is that no one knows absolutely that they'll always want to be with someone. I could suffer brain damage tomorrow and become absolutely unbearable and I wouldn't want my wife to want me in those circumstances.
I'd hope though she'd always remember the beauty she saw in me though and always feel love for the person that I truly was.
I'm clever. Well that's a first. Thank you for the compiment though.
I think that you are confused. I think that you think to love someone unconditionally means that you will do this or that for them.
It doesn't it means that you will love them no matter what they do.
You are spinning things around.
