Somebody please help me with this question?

my ex husband has been filing taxes as married filing jointly and forging my signature since 2001. I did not know till I resumed working and filing myself. I managed to obtain the tax records with the forged signatures for years 2001, 2002 and 2003. However I do not have the rest until 2009. I called the IRS and they confirmed that all taxes till 2009 have been filed as married jointly and listing me as the spouse. My question is will the IRS take any action if I send the tax fraud complaint form with copies of tax filings of years 2001 to 2003, with a note that I do not have additional proof for until 2009 and if so what kind of action? Would I become affected by this in any way? I had absolutely no idea what he was filing, his income or any such status of his. Also can anybody tell me which year e filing began in? For he seems to have filed few years as e file forms, since they dont need my signature, how do i prove that he has committed tax fraud? How can I emphasize my case to the IRS? Please help me, answers are soo appreciated!
