Is it normal to love other things than human?

being clingy and obsessing about a person isn't loving the person. if you suffocate and overwhelm people, they won't love you back.

i doubt that your plan is going to work.

I know a guy who pimps out his sheep. Maybe thats the answer?

i dated my cat once.

This is very common in Japan. People who don't feel the way do are giving you advice, keep that in mind. It's hard for you, more than most people understand. Find kind help if you want, you deserve it.

P.S A serious answer would be like this. Instead of practising what it is you call love on objects other than humans, whatever they or it might be, perhaps it would be more prudent instead to look at your definition of love. If its not working on another human, what is the point of transferring that same definition to a non human? You already know it does'nt work, so where is your satisfaction going to come from in loving something that is non human?

And also, be very careful about interpretting the satisfaction you may feel from loving something that is non human (however your planning on doing that I dont have a clue). But remember one thing, dont trick yourself into believing that the non human even wants your advances just because that object or thing is not able to express it so. Dont lie to yourself is what I'm trying to say.
