Because he's not being a man. Cowards have affairs and use them as "reasons" to end their marriage. He made a bad choice and wants you to go away.

If I could answer your question why, I wouldn't be here myself. I have read chats out loud to my H and he STILL says there is no affair.

BTW, how can he be living in NY, you in Tennessee, and file for D in Arkansas? Usually you have to file in the state you live in.
