Removing Conditions after a divorce - supporting affidavits

[davieinverness 1]

Hi all,

I am preparing to put my evidence together for my ROC I-751 with a divorce waiver based on us being in a bonafide marriage which has dissolved since the getting my conditional green card.

The primary evidence we have proving the bonafide nature of our relationship isn't very abundant. We have:

Joint Federal / State Tax transcripts
Proof of joint credit card use
Joint cell phone bills
Life insurance policy showing spouse as beneficiary
401(K) account information showing spouse as beneficiary

Given the lack of primary evidence I also want to include detailed supporting affidavits. I will be getting the following affidavits:

-My ex-wife, Sophie, explaining the circumstances of us meeting, becoming engaged, getting married and splitting up

-My ex-wife's mother, explaining the circumstances of the relationship between me and Sophie and it's bonafide nature

-My ex-wife's mother, explaining we were living in a property she owns, pays the mortgage for and where the utilities are in her name, which explains why me and Sophie have no joint tenancy/lease agreement

-My ex-wife's best friend, Agnes, explaining the circumstances of the relationship between me and Sophie and it's bonafide nature

-A very good friend of mine, Dominic, explaining the circumstances of the relationship between me and Sophie and it's bonafide nature, who came with me on a trip to New York to visit and stayed with Sophie and myself before I moved here

-Another very good friend of mine, Sean, explaining the circumstances of the relationship between me and Sophie and it's bonafide nature, who came visit us in 2015

-My brother, who came to visit us in New York City in 2014

-My mother, who travelled to New York City to attend our wedding in 2014

-My father, who travelled to New York City to attend our wedding in 2014

All of these people were present throughout the span of our relationship and know it was bonafide. What I want to know is what should they write in their affidavits to show that they know our relationship was bonafide?

Obviously this is quite stressful and sad for me to compile, so any help that can be provided is hugely appreciated, whether it is related to this specific topic or not!
