It's cyclical. Yes things change while we're in therapy; it's an alive relationship, not a static one. You cannot feel the same as you did before the rupture because there was a rupture there! That's like saying when you jump the Grand Canyon, you're disappointed because the other side looks different, doesn't have any cool hotels and tourist parts.

You are learning to be genuine in all relationships, even outside therapy. You want to (or I hope you want to) be yourself, no matter to whom you are talking. Now you get to practice being vulnerable and talking about difficult things all by yourself, without his hand to hold.
