Be honest tell him how your feeling and why. Gather your things and move out and file

I am in a very similar situation - scarily similar. I've been married for 6 years and also have a kid and I'm also in love with another man. I want to be with him and despite my feelings I'm going to leave my husband and be on my own until things settle down. If you feel that strongly then please don't waste any time it will only end up hurting you both.
