How did it make you feel? Are you sure it was him and not something pretending to be him?
I would be careful here and banish and cleanse for good measure. Obsession and misery go hand in hand and attract astral parasites who can start messing with you, as they feed on that and will do what they can to make it worse to get more.
Get your spiritual hygiene on point to avoid making problems for yourself.
Otherwise, let’s say it’s him, it could be a bad sign that he’s resisting, he made up his mind and is simply accepting that he has to process the pain.
The thing about lust and obsession spells is they don’t consider that a person can follow their head not their hearts (or their loins), and if you’ve argued before, well, what if he’s just he’s had enough?
