<human>: My husband of 11 years left me.

We had our problems, but I thought we were lifers.  We've been married 11 years but known each other for 20.  We have 2 young children.

I knew he wasn't happy for a while (but neither was I).  It was just the garbage of life we were dealing with (money problems, family stresses, depression, lack of sex).  We are in a very stressful period of time at the moment (sick extended family members, job issues), and I've been distracted for months.

He told me he was moving out to get some space to think.  Then it became obvious he was seeing someone else.  Then when confronted about it, he said he's not coming back.

I know:  lawyer, gym.  But I'm in shock.  I think it must be shock......it has been 3 weeks now and I still feel icy cold when I think about it.  I got sleeping pills from my doctor.  Husband is someone I don't even recognize.  He's extremely cold towards me and ONLY speaks to me regarding the kids.  Nothing I say breaks through to him.  In fact, he mostly ignores me.

I have no idea how to move on.  I'm dealing with intense anger (that I know working out will help) but I feel so stressed and out of control.  I'm not acting on the anger, but it sometimes feels like borderline rage that I have to stuff down.

I can't go no contact with him.......we have young kids who want to see them.  He wants them as much as possible.  I'm left here in tears while he takes them overnight.  Moving on will be a long tedious process because I'll still have to see him REGULARLY because of the kids.  And I'll have to hear about his life.

My heart is broken.

Summarize the given text in a few sentences.
<bot>: husband moved out to think, then told me he's not coming back.  We have 2 young children and have to co-parent.  How can I move on when I have to have regular contact with him?
