Sorry but that’s too much , if someone tend to do something with your family and do something wrong with you repeatedly (if it’s cheating then no other chance) , and you still don’t do anything then it’s not love/ obsession/craziness etc it’s just stupidity, no one can love that person.
Losing love for someone because they did something wrong , that doesn’t mean you never loved that person , it’s just they never deserved it .
Even it that’s metaphor to measure the love that’s so wild tbh .
