solid two wrongs don't make it right. All addictions/behaviours that negatively impact a relationship (as flagged by a partner) need to be brought into check, addressed and determined appropriate or not for that couple for the sake of their specific relationship....every couple has their own balance.
As I said before the what, when, how, quantity etc of the drink/activity is irrelevant - it is the impact on the relationship that determines if it is a problem or not for that person/partnership.
The OP is an intelligent woman - she can make her own informed decisions about how she chooses to reward herself and relax - ie by positive activities or negative - also the risks she chooses to take with her own health by her "heavy drinking" (as determined by health professionals - she is consuming 10 units in an evening - when the safe LIMIT is 3)....is her call.
Although I am alarmed that she seems to believe that her approach to diet and exercise will somehow compensate -- if you look at the extensive list below - (except for BP & Obesity) - her "healthy lifestyle" will not prevent the following:

If you drink heavily you have an increased risk of developing:
Hepatitis (inflammation of the liver).
Cirrhosis (scarred liver). Up to 3 in 10 long-term heavy drinkers develop cirrhosis.
Some cancers (mouth, gullet, liver, colon and breast).
Stomach disorders.
Pancreatitis (severe inflammation of the pancreas).
Mental health problems, including depression, anxiety, and various other problems.
Wernicke's encephalopathy - an alcohol-related brain disorder treated with thiamine (vitamin B1).
Sexual difficulties such as impotence.
Muscle and heart muscle disease.
High blood pressure.
Damage to nervous tissue.
Accidents - drinking alcohol is associated with a much increased risk of accidents. In particular, injury and death from fire and car crashes. About 1 in 7 road deaths are caused by drinking alcohol.
Obesity (alcohol is calorie-rich). One glass of wine has as many calories as a bag of crisps and a pint of lager is the calorie equivalent of a sausage roll.
Damage to an unborn baby in pregnant women.
Alcohol dependence (addiction).
In the UK about 33,000 deaths a year are related to drinking alcohol, a quarter due to accidents.
I am not a tub thumper -- I have a problem myself which I am trying to tackle.
