Hi Sherlocked,
Well done on looking for help.
I would advice against watching your boyfriend play. Sooner or later you will be watching him win/have luck etc and you are just teasing the addiction. Would he agree to not gamble when you are there? Better yet if he stopped gambling at home you could then install a blocker so that you can’t be tempted at all to gamble online.
Why are you expecting the week mark will be hard? Is it payday? Or a usual gambling day? Whatever reason use your awareness/knowledge that it will be a vulnerable time for you. Have extra barriers in place, have plans to fill your time and thoughts with non gambling activities.
keep posting.
