Its crazy I know but try your best to act like a Stepford wife for now and be happy and loving. Deal with your real feeling in safe enviornments like therapy and here.
Actually, I'm not so sure that the Stepford Wife act works. The last time we reconciled, I was total Stepford Wife, and I did a pretty good job for a little while anyway but there was no way I could keep it up long term - it was totally ridiculous.
Recently when having a long conversation with my H, he fedback to me that during that time, he knew I was 'not myself' and he was wondering when it was all going to fall apart. It did eventually, and then he said he preferred my usual self- just without the criticism/outburts.
So, I'm not on the whole Stepford wife thing - it's inauthentic and disingenuous. I would instead say be yourself, just watch out for the areas he complained about.
I think it's much better to be self-accepting and overcome one's weaknesses. Long term it feels a lot better as well.
