Umm, maybe you and your partner might start a new heath routine together, drinking healthy shakes or smoothies, working out, walking ect and trying to enjoy life without it. A support group might be helpful, but there are other things you can do and I think getting into a health routine, eating healthy ect, would give you some incentive to keep doing it. Also, have a account that you spent your money on the weed and instead use it for your pleasure, like going to a really nice restaurant ect. good luck
