How would she know that he looks at other women?
(Unless she follows him or has done it before and she is assuming the same happens)
Drinking until hammered and driving is irresponsible and with the BAC so low now you can't really drink much anymore and still drive.
It's really up to them to find a middle ground - if you're married and still partying every weekend at nightclubs and/or titty bars maybe getting married should have been put off. But at the same time people need to ease into change and not be forced to because ultimately that never works either.
ps. Sorry to talk about you like you're not here.
Good Luck
fix this now - do whatever you need to but do it now so both of you are happy
