I am married 3yrs before. After two weeks she left me and went with someone.I put divorce case and its in progress. Now she proclaim that she is saying that she had sex with me and she like to live with me.
But, I had sex only one time with her (partially did) before 3 yrs.
So 3 yrs gap no sex..
So, Now I'm saying that I had no no sex with her.

Can she prove this through any medical test.?

PLease give exact answer, such that it may useful for getting me divorce??

The exact answer is no, 100% no.

There is no way you can prove this either way.

You can't prove it either direction. The fact that she left you for someone else should be good enough.

SImple answer here... its NO.
