Affidavits can be from anyone but may not carry much weight although may help for high risk countries.
If you or your spouse are including one from either you, him or both, you should title it Evolution of Relationship letter and detail out your relationship/history/background.
Signed in ink since it is an affidavit.
Sample below.
Hope that helps!
