This is a question we cannot answer well without a lot more context.

Since this is your first post here, we don't know anything about you, and thus can't really speculate as to why your therapist would disapprove of going to bars, (I assume by "balk" you mean that they seem to not approve of it) but there are many possible reasons. As just one example, if I were a therapist and I had a client who had issues with alcohol dependency, I would probably be worried if they were going out to bars every night.

So, feel free to give us some more information, and maybe we can answer better. Or, what I think would be the best option, is to discuss it with your therapist, and ask why they have that reaction.
