Did the two of you socialize together with friends? Are there people who've heard your STBXH call you his wife? Who've seen you do loving things together?
Those are probably the kinds of things that your L is talking about, but you should ask for more information.
If they want to prove consummation...that's a little different story.
my FIL wants to annul the marriage (married in 2008). it is a money issue. if he can "prove" this wasn't a real marriage but only something I entered into to take control of STBX's money, then there'd be no payout.
FIL constantly screams about my breach of fiduciary duty. i had no fiduciary duty because i didn't control my STBX's money, only the money that was funneled into the joint bank account.
i don't have proof of consummation; however, i have erotic emails we shared going back to 2006, and i'm willing to submit those.
no, we didn't socialize in the traditional sense; however, my STBX referred to me constantly as his wife, and posted apologies to me on his Facebook. Put memes up about how he loved his wife, mentioning me by name.
i'm just (just?) tired, actually completely worn out, by FIL's antics and blustering and posturing. he's a bully, and he bandies lawsuits around about how he can charge me criminally for misappropriating money, which i also didn't do.
like i said, he's a bully. and i'm limping today.
