Good luck.

I will be eating vegetables all the time if I marry my girlfriend.

I had been eating vegetables before I got married.

I have been eating vegetables recently.

By the time I am 60, I will have been eating vegetables for many years.

Progressive aspect needs a “be” verb in some form. Don’t confuse it with a gerund, which looks like an -ing verb, but acts like a noun.

Have fun!
