I've mentioned Retro to her, and she looked at their homepage. It didn't appeal to her.
Your W is willing to go to MC, but not Retro? My W really, REALLY didn't want to go. She finally decided to go just to "communicate" better with me during our S.
It's a weekend on communicating. Costs next to nothing unless you CAN pay (which you should). I signed up for the one in two weeks and they are asking a $550 donation for the couple. We are in dire straights right now with money, and I know we can't pay that. But, the retro people understood completely - especially since we are a young couple.
Maybe give it another try. Tell her that you're interested in going not to improve the M or make it 'work', but just to understand her better and communicate more.
I wouldn't pursue it too hard though. Maybe talk to MC about it? See if (s)he recommends it. Maybe talk about it in MC.
