I think for me the answer to the first question is yes, but the other questions you raise do make one think which is great
I think if you truly love someone for who they are, of course you hope who you think they are is really who they are, but if you discover the real person and love them then that is best.
Often people think they love someone but also want to help in their own mind improve them but changing them to make them better
I think thats a bad idea, by doing that you are trying to change the person you love into someone different and that person you may not love or love as much
And you know what happens then? We change the person and then leave them because they are no longer the person they were when we met them. It is a hilarious but very common scenario. Thank you for your lovely comment and your thoughts about this. 💚
