Hi Greenstar and welcome. Well done on looking for help.
Now, while you are “licking your wounds” it is important to put as many things in place as possible. Then you will be prepared for when the pain fades and the urges may return.
Well done on excluding from those sites, how about getting a blocker as well?
If you have lost about a fifth of your savings then i would also strongly recommend putting the remaining 80% somewhere safe. Maybe in an account only your wife can access? Have you spoken to her about this?
Keep posting, keep taking positive steps.
