Hello. I'm A 45year Old Female. I Am Also Very

Hello. I'm a 45year old female. I am also very angry & depressed. I have been married for almost 8years. my husband has been lying to me since the day we met. Cheating & really likes the attention of younger girls. my teen daughter is also the attention he likes. Just this past year i started putting my phone to record & leaving it behind to find out exactly what he was doing while ai was away. I Believe i hear his whispering and having sex with another girl. I Believe this to my core that im hearing this happening. he said i need help, that im hearing things. It's not possible cuz no one has ever been in the house. Im asking, Could he be telling me the truth and i am so consumed by his cheating and lying that i'm making this up in my head? And Why would i ever want this to be true? im also a recovering addict of meth. so could that have something to do with it if so. Again,, I BELIEVE I'M truly hearing him with another woman. Please Help Me. It's got me so angry that he could and would go to such great length to lie. i've attempted suicide 3 years ago cuz he couldnt admitt to stuff, then came my guilt for accusing and lost hope. but turned out i was right.......
