Well maybe put into consideration what your hobbies are, if they are healthy for you and your relationship, and if they include your wife.
If your hobbies are healthy and considerate for all, then maybe you two are better separate or she needs to learn to respect that. Which also means, there might be another underlying reason for why she really left you.
Buttttt if you were being an inconsiderate blind douchebag for too long drowning yourself in bad habits......that miiiiiiight be your own fault. Change your perspective and see if anything is possible in the future.
