Having 1-2 glasses of wine a night is perfectly normal, and assuming that you're not a super tiny person, not an unhealthy amount of alcohol.
However - feeling like alcohol is the "only way" you can unwind is a problem. You have an alcohol dependency.
If I were you, I would brainstorm a quick list of other potential ways to unwind (sex, board game, bath, book, husband gives you a massage, yoga, going for a walk, etc). Come up with at least 8-10 of them. Then pick one day a week (say, Tuesday), and promise yourself that for the next two months, you'll have ZERO wine on Tuesday, and that instead, each week you will try just one of the things on your list. Then, on Wednesdays, jot down a quick note as to whether it was helpful/awful/fine but not great.
Then re-evaluate in two months. If Tuesdays were torture, or if you couldn't do it, you have a problem, and need to talk to someone.
If they were fine, just not great, and you found at least one or two things that made it pretty solid, then great. Try and keep up with those one or two things instead of drinking once or twice a week, and pat yourself on your back for surviving the little kid years however you can.
