I have just made an appointment for a session with a relationship councillor for my DH and I. I am very sad and fearful that we have got to this stage and all I really want is to shake off the problems and be happy and content as a family. Unfortunately 'D'H seems to think the grass can be greener and I have no idea what he is aiming for. He's a very closed book and I am concerned that I will just end up doing all the talking as usual and he won't communicate even although it's his idea to go and talk to someone now after me suggesting it a few months ago.
I very much want my marriage to continue (and be a happy family) but am aware that I can only manage my own responses and am not able to change how he feels. 
There is a long history of deceitful behaviour on his part and I know the general response would be 'leave the bastard' but we really are extremely compatible otherwise, we don't row or have any other discord at home at all. We enjoy each other's company, spend all our spare time as a family and both adore our children. We are also overseas in our dream location which was a joint goal for 10 years and it's every bit as good as we hoped it would be. I am just so sad he's prepared to dump all that and I REALLY want counselling to work. I have seen many marriages break down recently and in EVERY case even the most amicable split descends into hatred alarming quickly. DH's parents marriage was a case in point and I do not want to repeat history with my children.
Everyone we know would be shocked to the core if we split. We have never given any indication of issues to anyone else. (hence the username). Talking to someone about it all is going to be really hard and I am dreading it.
How do I approach the session and is there anything else I can do to get my life and marriage back on track? (and how do I get rid of the pit of doom in my stomach?).
Thanks.
