What would you do?

Maybe if it is not suspecious. I would let her choose her choice I guess.

Their relationdhip may be on the rocks. She may be less committed because of their status, thus accepting calls from other men when she is already in bed with your friend. It would be acceptable if the calls are important. The big question is does your friend still loves her and want their relationship to remain intact? One way towards making a final decision is for him to have a slow talk with her. Get a mediator if things are difficult and he thinks it is best to have one. At the moment I do not want to be judgemental towards them. What I am prepared to suggest is for them to be open on their current feelings towards each other. If her feeling towards him has changed then the reasons or circumstances leading to this should be made known. Only then a real decision can be made. Separation should not be the first option. all the best, rosdimy

I would ask why the heck a single woman is calling him at night and asking him to go on a date!

I would simply tell my common law wife not to go. If she insists on going, then I'll tell her the relationship might be over. Sounds too simple but it is. It's better to end the relationship now than to have the partners go behind each others backs and have affairs and let the relationship continue even if both partners are sick of each other. Anyway, Happy new year.
