Ive been in a similar and apologies to any blokes that have posted here but i thougt a blokes eye view is a good one

I was in a similar situation with my ex wife and we tried to restart things as was suggested but both parties needed to be willing to do this. SHe wasnt and sadly we split.

I think that him going back to his moms for a while and the pair of you sending yaselves back to the dating stage is great try and reignite that spark b4 it is gone for ever.

Please do let us know how ya get on
