"You're not you"

"Why is it that we want the ones that don't see us, instead of the ones that do?"
Just watched a drama about a wife who diagnosed with an ALS disease. and how the husband being such a good one, taking care of her everyday but cheating behind her.

Is it happen in a real life?
I mean it would be scary if things happen so harsh like that. It is better to show up how you feel than showing up your fake face. It must be more hurts than hearing the real truth.
Just like what i said before, that sometimes we want the ones that dont see us, instead of the ones that do? it is so true. I feel that too. We know that there's someone out there, who wants us to be with them but we dont want them to be with us. I don't know why things like that exist in this world. Why can't we just liking each other without being rejected. Why God creating things like this?
Why?
