Finally realised that he is having an A!!

It sounds illegal for your H to withhold maintenance, first of all. Regardless of him having an A or not, if he does that kind of crap, you really do need to have protection to ensure financial support! Maybe you can see an L about that before you expose?

And see what else you can find out about their friendship so you have more info to give the H when you do expose...maybe it's your turn to follow her around. Well get a friend to at least. I don't know the details of how you would do this, but it's an idea!
