If you are chasidish maybe you want to contact R shmiel neiman from Monsey. I don’t know him too much but from the parsha that happened a few month ago I got the impression that everyone agrees that when it comes to Yungerleit that are struggling with yidishkeit he understands them well. especially if your husbands nisyonis comes becuase of kedusha nisyonis and lacking satisfaction and the goyish world is pulling him because it makes it look that there he can enjoy … (this is the most probable reason) he should be able to give you good advice.
You probably may want to also search for support groups for your scenario . i am sure there are a lot of them because the problem is more common than you think.
