If you are getting SSDI, your marriage should not affect those benefits.
If you are getting SSI, then your marriage likely would affect SSI.
If you are getting both, your SSDI will survive your marriage, but SSI probably will not. SSI is a welfare program and household income matters.
Spousal benefits wold only be an issue if you were at least 62 years of age and he was also receiving Social Security. I am not getting the impression that either of you is that old.
