Oh ok makes sense. He is/was feeling very angry and aggressive, you probably had a verbal argument/heated exchange.. or that’s what he wanted to do lol give you a piece of his mind. Knight of swords is always a very negative and aggressive/conflict card. Always shows up as abuse in my readings, usually verbal/mental but sometimes physical. He was probably thinking really mean thoughts about you, swears etc. It’s THE most aggressive card in the deck, it’s full of energy and wanting to rush forward and cut with the sword.
3 of swords R, is actually pretty positive. With the reversal, it’s healing. The swords are falling out. So this tells me, when you broke up, he was already pretty much healed and over you and the relationship, the grieving process had started for him awhile ago whether you realized that or not. People don’t break up over one thing, it’s usually a build up of things over time. So this tells me he WAS really hurt, at one time, that’s the normal 3 of swords, but when you broke up he was already healing/healed (3 of swords R).
6 of pents means he felt less than you. In the context of the question, how he felt about the breakup (remember context is everything you always refer to the question) it literally means he feels less affected than you by the breakup. 6 of pents is all about imbalance. Someone is giving, the other is taking. Someone is more invested, more interested etc. Since his feelings is the 3 of swords R, I know it’s him that’s giving less since again he was already checked out and over it when you pulled these cards. And if you’re still pulling cards on him, again, logically you’re probably the more invested one.
Given these cards it’s best to move on
