The attraction between you runs strong and deep, and may take on somewhat overwhelming proportions. You exert a certain amount of control over your lover's behavior -- subtly or more forcefully influencing how they feel, how they dress, how they behave in public and so on. This could lend the relationship more of a parent-child feel than that of two equals in love.
Obviously, this isn't the most fun or pleasurable aspect to deal with, though it could make you feel closely bonded together, mutually dependent on each other. This aspect could stunt the emotional link between you; it feels difficult for your lover to open up to you, because they feel afraid of your criticism. Unless there are other aspects to warm up your connection, this could be a troublesome influence to deal with. You might even end up wondering why you two are together, when you don't even seem to like each other the way you are! There is a component of guilt or obligation that holds you together, and that's not the best glue for a loving, healthy relationship; but this aspect also brings a level of security to the relationship that you both feel better for relying on. You know that you can trust each other, and that counts for a lot.
