"But I guess we just have to take life as it comes, ___ we?" Should i use won't or don't?

I have a question about whether I should use won't or don't in the blank space and why?

But I guess we just have to take life as it comes, ___ we?

I know that won't is used for future but I'm not sure.


Solution 1:

You need "don't" here for concordance with the present tense in the first clause.

"We'll just have to take things as they come, won't we?" uses the future tense.
