My H said many similar things too. He no longer loved me, he wasn't happy for months (then changed to years), I was to controling, why should he stay if he were unhappy. His OW was not out in the open yet - so my changes he saw take place he knew were real changes b/c I did not know of OW yet.
Think about what she says her 'real' issues are with you - are there things you can change, then do it! Do the changes for you! GAL and detach from her. She may change her mind - my H did - it does happen!!
