@sam911 it is very sad when something that was once so right turns very wrong. But this isn’t a love/hate colliding thing... that is slightly different. This is when love goes sour and there are things in between that cause a bitter tase in ones mouth that eventually creates a feeling of hate.
Love and hate colliding can lead to someone who has a feeling of love being used and taken for granted by the person that is more hateful (maybe not even hateful).
This to is a sad state of affairs for both parties.
