Steve and Shirley please help me!

I was robbed at gunpoint and my spouse’s teenager set it up and watched.  My children were there.  It was very scary.  My spouse never disciplined his child for this we don’t have a good relationship, blended families are not easy but if both adults are not on the same page it won’t work.  I’ve had to deal with disrespect, theft, etc but the icing on the cake was the robbery.  Forgiveness is the hope that the past could’ve been different I’ve told my spouse I will forgive in my time.  I’ve been asking God to help me with this my spouse and I have decided to go our separate ways, he wanted us to work it out but I refuse to live like a prisoner.  We have children together and their happiness is important to me.  I’ve never been rich but I feel like I struggle more financially when he was in the home.  I’m still struggling and I pray every day that things will get better please help me, thank you.
