Yep! in fact codependency occurs in every relationship, unless you are much older and mature, but it does happen, it is part of the enmeshement stage, but if we stay there and don't develop a healthy distance, then the relationship won't develop between two people, and both will feel trapped, unable to express themselves, then we hide parts of ourselves from our lovers and then we resent them and love them, but it can be helped by working on yourself, so that when you get better, the whole system will improve, which then encourages your mate to take a look at himself, but some don't change, they rebell against change for fear you are withdrawing, so you must communicate clearly and openly, which is the opposite of co-dependency anyway/

It makes total sense...My best friend, who I happen to be codependent on and who was on me, just got into a relationship where they are both VERY codependent on each other...It's a HUGE mess...
My point is that it IS totally possible for both parties to be codependent on each other. If you start working on yourself (which you need to do for YOU, in order to be truly happy and healthy) he is probably going to panic if he doesn't seek help as well. If you guys truly love each other and are meant to be, you can do this together...as long as you are both willing to do the work!!
