I haven't washed the dishes yet, but i 'm going to
Yes, Adam619, that works. Notice that "am going to" is not the progressive form of the verb "go" as in I'm going to the park but expresses future (the main verb "wash" has been elided):
- I haven't washed the dishes yet, but I'm going to wash them soon.
The future is possible and is semantically consistent with "intend to." If the person says "I intend to," he/she means he/she has decided to do the washing sometime in the near future.
