I would like to know if it is possible to say "I was supposing..." or does it always have to be "I supposed..."? The example for what I am thinking of would be the following sentence:
When we talked last Monday, I was supposing I would have a lot of free time this week to prepare the documents. However, I turned out to be quite busy.
Last week I was supposing, I'd meet you in the office one of these days. I didn't know you went on holiday.
Are these possible?
