US Immigration from Guatemala

I wasnt sure exactly where to place this question so I decided here as the journey began with a CR1 Visa.

Long story short, after him having lived here almost a year and a half it was decided divorce was best. His 2 year green card expires in July.

My main question is, do i have to stick around for his 10 year green card to be approved? It expires in July and I know the petition could be started even 6 months before, or so I've read. He would like to stay as he created a life here with work, friends, etc... things just didnt work out as expected with our relationship and we would be ending on a pretty good note as it was a mutual decision. I kind of just want to submit the divorce already and move on with my life but not if it affects his chances of obtaining the 10 year green card, if it affects it at all.

Any info would be nice, thanks!

hello!
my husband's USCIS case was approved a couple of days ago and we are trying to gather all we can right now. We need a sponsor and I cant be it because I did not make enough money on the last 2 years, but a friend of mine is willing to sponsor him, but she just has one question. She will apply for citizenship in the next couple of months and she wants to know if being a sponsor will not effect her when applying for citizenship. thanks in advance
