Heather good for you for standing up for what you are willing to accept.
I do have one caution and that is if your husband is using porn and masturbation as an escape, too "tune out" with it may be very difficult for him too kick, even I you're having sex. One thing I was trying to get at when I shared with you some of my experience with porn was too say that it isn't always just about sexual fulfillment. If your husband isn't very self-aware the way he uses porn allot of issues may come up and be a big struggle.
Although his difficulties are his to deal with.
Separate isn't such a bad thing especially when a boundary is being established.
