You need ask your self if you are truely happy in the situation you’re in.
Partner, house, job, car anything and everything.
Some people find they’re unhappy because they have lots of bills or find a problem and cannot work a solution.
If you were truely happy, you wouldn’t ruin plans or days with the partner. You would make separate plans to get blind drunk that don’t affect what’s more important. If you had no reason to drink for example…
