How is everything going? I know that you are preparing for a travel back to Taiwan sometime in April so you must be extremely busy now. I am also excited about your coming return.

Lately I have been revisiting my word list and two sentences caught my eye.
1. They've only just met - isn't it jumping the gun to being talking about marriage already?
2. The company's dominance of the market is gradually being chipped away.
My question is if I don't use present continuous tense in the two sentences, would they convey different messages?
1. They've only just met - isn't it jumping the gun to talk about marriage already?
2. The company's dominance of the market is gradually chipped away.
When can I use present continuous tense like the first two sentences?
I really appreciate all the help you have given so far and wish you well.
