That sounds all too familiar to me!!
I was with my husband forever before he proposed. And thats what I wanted most of all to happen...and when it did and we went to pick up the ring, I told him to ask if there was a return policy. I will never forget his face and I couldn't believe it myself.
And like you said, this is just an example. For instance, I want to join a yoga class. I had joined before and loved it, but had gone with a friend. This time it will be on my own, and I just can't do it. I have been talking about it for months now.....and my husband can't understand why I can't go join. I cannot make up my mind whether I want that commitment to go or not.
I see a therapist, and am honest with her about this, yet nothing has changed yet. I am optimist it will. Hang in there and I will too.
