Re:advice please AmyMarie1972: Hi,
Jealousy is a very powerful thing. It does not necessarily mean that she still has feelings for you that she wants to rekindle. It could mean that she doesn't want you but she doesn't want anybody else to be with you either.
It is a positive step that she is seeing a counsellor but it is also a positive step for you that you have started to see other people.
I understand that if you could have any wish in the world you would wish to keep your family together, have your ex back with you but wishes seldomly come true.
Continue with your life as you have been. Keep the friendship alive with your ex but don't expect it to turn into anything more than that, especially while she has problems that she needs to sort out.
It's hard I know, but you can and will get through this.
Best of luck
