You're using your negative experiences of people to say that all people are bad - and so basically them - you're sticking with pets.
Just because you have had a bad experience of other human beings that doesn't make you right in saying you prioritise your pets life over that of say, a human child.
You say "oh my cat is good" "my cat is nice" "my cat is honest" - it's because you feed your cat. Stop feeding your cat - see how long it is nice and honest and lovely for - see how long till it just s off and finds a new home. I have cats myself - cats are nice and happy because you're feeding them - if I fell on hard times they'd off.
Seems like your mistrust of humanity means your missing out on life - you're putting the feelings you should be feeling for other people (ilke say - hmm i dunno - your girlfriend!?) into animals - because you know there's no chance they will hurt you. It's like that saying - the walls you build up to defend you will also contain you.
It's your life - your call if you want to let it erode second by second loving what is effectively a fairly stupid animal that is loyal not because it particularly likes you - but because you feed it.
