hi blue13, and
it may not seem intuitive, but its a good strategy when you first get into couples counseling, to check getting everything out, and instead do a lot of listening.
couples counseling can do a marriage a world of good, or it can do it a world of bad. it goes badly when one or both parties enters with an agenda to fix the other partner or bring the counselor to their side. your wife may do this, but an experienced counselor anticipates this (they are used to it) and can work with it. if you do the same thing, theres a high likelihood that things will just explode.
how long have the two of you been together?
