Could it also be that he feels she is his sense of security and holding on tightly to her (holding onto what he has) as he doesn't want to loose her. He want to keep her close to him. In the RWS he is cluching a penticle close to his heart, because it is important to him.
Althouh as other's have said could be a tad possessive as well (there seems to be a duel message in this card) but I also find that things that we possess in our lives does give us a sense of stability and security and when those things are taken away our world becomes shakey. I think the majority of us do tend to cling to what we have and don't want to lose what we have worked so hard to gain in our lives. I don't know, I call my husband, MY husband. I guess I can be a tad possessive of him too. I get this card often for my husband. He is very careful about money (tad frugal), but he is in no way stingy with his love or affection.
On the positive side of this card, maybe as well, he could feel content, happy and comfortable with her in his life. As Alta said bring her into his world, shelter her. Does the 4/p usually have a negative connotation to it as in GoddessArtemis post? This thread has really given me food for thought about this card. I can see all of the posts as possibly appying, so which one is it? Would it depend on the surrounding cards, or do you pick one from your intuition? - rwcarter "The correct interpretation, of course, is the one that's right at the time for the question you're answering...." but how do you know it's right? gut feeling? You could really screw up a person giving the wrong interpretation as in is he feels she is his possession or does he feel she is an important part of his life?
(still a novice BTW)
