While she may be talking to her C about important issues, and that's always possible...what's not happening by her seeing someone alone is this....she's not learning to talk to YOU, which is in reality one of the things you are telling her you need. She has her emotional outlet, her confidant....so she doesn't need to talk to you.....and by seeing a C on her own, she's not likely to start.
A good couple's therapist is going to teach you both how to communicate more effectively with each other...and help you break down the barriers when it comes to communicating about things that are tough....or talking about things (like my H) that you just are used to talking about with someone.
