There is something mysterious, even confusing between you that always obscures important factors -- your true feelings for your partner, perhaps, or your identity as an individual within the relationship. It might be that they simply don't see you for the person that you truly are, because something below the emotional surface of your relationship muddies their view of you. This is as difficult to pinpoint as it is to understand, but the effects are felt by both of you.
You might have hurt feelings that you refuse to talk about, and you insist everything is fine, even though both of you know that's not true. Or you might make a judgment of your lover -- not a positive one -- and even though you insist you're not being judgmental, the effects are felt just the same. In some way, there are hidden emotional influences that affect your relationship, and you both have a hard time bringing them to light. The normal methods of doing so -- verbal communication, even professional counseling -- might not do the trick. The best way to deal with this confusing, elusive energy might be simply to withstand the confusion while making sure that each of you asserts yourself as an individual. The danger here is that one or both of you begins submerging parts of your personality in deference to the relationship, but that's not the right thing to do. Being yourselves, as honest and straightforward as possible, helps.
