text: i need help for my mom.? my mom went through a divorce and her ex gave her a std (hvp) can she sue her ex she has proof that he gave it to her. it is in the state of michigan. it is still too hard to prove in a court of law... you can prove cheating on his side, but he could say the same about her.... how can she prove she didn't?!  they here those kind of cases all the time.... std's  are a real hard thing to prove either way....unless it is aids....good luck....
