Is it time to file for divorce?

I have been married for 6 years. My husband and I have two little girls (age 5 and 2). My husband was recently sent to jail for 3 years (theft charges) possibly able to get probation in a few months. For 6 years I have been by his side for good and bad. He has had multiple affairs that I have tried to work through and just weeks before finding out he was being charged and going to jail I found he had a two year affair with another woman. He kept the criminal charges a secret from me somehow and didn't see this coming. I was a stay at home mom and running around trying to find a job in order to have money for our mortgage, food, etc. I can't believe I'm in this current state and am feeling every emotion possible right now.

I've had some people try to convince me that I made my vows and should stay with my husband but part of me feels haven't I dealt with so much already and don't I deserve better for myself and my girls. Is it time for a divorce?
