Dear Sandy
I am not sure if a good psychologist is going to give you any directions to follow but, instead, helping you to make your own decisions. That can take sometime but for sure is going to support you.
I can’t tell if confronting him is going to be good. Instead maybe you should think what you expect from this confrontation? After that you can try to see if showing the pictures is the best way to reach there. From my prospective it will just tell him you have been worrying enough to follow him and he probably need to be more careful but I don’t think it is a good way in trying to change him. I know it is hard, but you cannot make him change. He must wants to. Just you can tell how much suffering and how it is affecting your life and your children. Honestly it is a personal decision but consider that, sometimes, is better split for a while so you can focus on your wellbeing and take a better care of your children than living in a suffering. I understand that it is hard to leave any situation which we are adjusted to. You wish to be happy but are you happy now? So how can you get there? Is it fighting for your marriage and your husband? So go for it. Look for a good psychologist specialized in addiction and use all resources you have. Maybe even loving your husband a lot and tour family you know that relationship can’t bring you happiness anymore. But it is also scary, because it means you will need to make a huge change. And big changes are scary. But they are also necessary in life. I hope I could have helped you.
Love
Claire
