This sitch has been going on for so long that I have forgotten where we started. Have you asked your wife to go to counseling with you? It seems to me, with the gift of the bicycle and the Father's Day card from the dog, that she is trying in her non-verbal kind of way, to say she is sorry. (Granted to those who want real penance, not to any great depth, just a little gift/card giving kind of sorry.) To say that you and your wife have serious communication problems is an understatement. You could benefit from work on communication within the marriage, if you could find someone to help you with it. Perhaps, if and when you do decide to talk to her about more than shopping or the dog, and if she says that she has changed her mind about leaving, then maybe you could suggest that the two of you go to a marriage counselor and learn techniques for better communication within the marriage.
