Should I move on with my life?

My husband and I have been separated for a little over 8 months. We have been going through marriage counseling. However, I recently found out that he has been having inappropriate relationships with other women. He made a mistake and sent me a text that was meant for someone else. I also found messages on Facebook about his relations with women. I love my husband but Im so tired of the heartache. When confronted all he doea is lies until he finally he reveals smidgets of the truth. Im thinking Divorce.
