ok so I am not single/divorced and don't have twins but certainly know how lonely and isolating it can be being stuck at home with a child and while I think a night out would be lovely I think baby steps is a better approach and she might be more likely to accept. So instead of a night out straight away (and I am assuming you would watch the girls all/most of the night) how about a day off or an afternoon/morning off cause it sounds like she probably has never had any time off from the kids and might be overwhelmed at the idea of a whole (or most of a night) off. Also if she is anything like me she might appreciate the peace of going to the movies by herself and maybe a coffee and magazine after to read in peace

You and your husband are wonderful for wanting to help her and I hope she let's you
