Do you chose true love over staying in a marriage for the sake of the children (ages 16 & 11)?

Do you chose true love or staying in a loveless/hateful marriage for the sake of the children (ages 16 &11)?? Have been married for 17 years and the last 6 have been nothing but fighting and leading seperate lives; meanwhile the children suffer through hearing the fights and then deal with the silence... Do I move on and find true love or do I wait till the kids are grown and out of the house?
