I'm not sure I understand though, strength is not about restraining feelings then but about having feelings that are healthy unlike the Devil?
My take on it is: The feelings themselves are not healthy or unhealthy, but how you deal with them may be the one or the other. If you surrender to a certain feeling or desire total power over you, that is the devil. If you fight it and try to keep in under control, that's the chariot. If you acknowledge it, incorporate its energy and it doesn't destroy your balance one way or another, that's strength.
Where does strength come from? More importantly, where does lack of strength come from? One answer is inner conflict and battle that drains our energy, different aspects of the self fighting each other rather then working together towards a common goal. Strength then comes when all of 'me', both the more primitive aspects represented by the lion and the 'higher' aspects personified in the maiden, are in peace with each other and all this energy can be used for a more useful purpose.
Edited to add: For example, if the person has powerful feelings for you and that is in agreement with their intellect, that would make them feel strong.
On a different note entirely, I just remembered something else. On one occasion, I have also seen the maiden and the lion as representing the two people in the relationship, with one being dominated by the other. The querent confirmed he did indeed feel this way. Strength, and the things we've all said so far, would then be the advice.
