We know straight from Neneko that if you love her she will return that love ten-folds. Her 2nd sonh showcasing T-T and her eating "cake". T-T fed her small bits while she went beyond with her spoon and even gave him a strawberry on top of the slice. I really think, if Neneko loved the right person this would never happened and they would be the cheesiest couple to ever lived. Though yeah, to the outside eyes, it may seem like a competition between the two, but to be loved properly might changed her as a whole. I think she got unlucky stuck with this Tsukasa Tenma the pianist™ who choose the easy way out (locking himself in sekai) and left her alone, instead of communicating. She could've been happy and thriving... She doesn't need to think she's being taken away her rights to love... she just need someone right. Someone to actually magnify her love correctly.
She's innocent...
