Residual feelings are a fall out from something ending. You can love someone that you hurt or hurt you.... just don't force it.

If I tell you to F off and I'm logical and not emotional about it. Just because you want them to organically die off doesn't mean I have to let you have it. Especially when you are the one that caused it. That's SELFISH and disrespectful to the person you claim to love or have residual feelings for. Let me get over you in my time *rolling eyes*

That's why scorpios get a bad rap... it's because it's always about your emotions.
