Adjustment of Status - I-485

Hi we are same sex couple that is due for interview in a week. we didn’t know the interview would come this fast, we don’t have a lot of proof for out marriage yet. We mostly have pictures, joint bank account and lease. We moved to our apmt just 3 months ago so we only have 2 months of electric bill. Even our internet bill only says ny wifes name and not my name on it. We added my name but it doesnt appear on the bill. Out phone bill is not together either, i’m still on my family plan with my mom since i still have to pay off my phone,(still over 600$) and my wife is with our other friend. We thought when i have a few hundred left on my line then we can pay it off and be on the same phone line but it’s too late since they scheduled theninterview so quickly.(thank God). Still problem is we don’t have a lot of proof for our marriage. Lawer is asking us for more, we have credit cards together, but we haven’t been usuing it since we are on tight budget. And the bills still only ever shows my wifes name.

Is it possible for my wife to add me to her health insurance when i don’t have ssn? We filed for her to petition me in August and didn’t know the interview would come this quickly. In 1 week, dec 20. Only 4 months after filing. She tried to add me but fidelis/marketplace asked for my ssn which i don’t have yet. We didn’t know interview will come first before the ead and ssn. So, question is what’s our option with insurance before the interview?
