Yes, you are making the right decision. You and the kids and your dog all deserve much better. Yes, there are men out there that do not act and do things as you DH has been doing. When you look back a year from now, you will see the big turning point in your life and your children's.
I will definitely be praying for you and your children. I, also, agree with the posters who worry about your safety and for your children. Maybe you do not need to voice this to him. Just do it!
You are a wonderful woman who has many women who back you from this website. We might be cyberspace friends, but we are friends who do truly care for your well-being and for your children, also.
Please let us know ASAP how it goes for we will be praying for you.
Hugs to you and your children,
Cheryl
