My oldest daughter is not his. I had her when I was a teen. My husband and I met when she was 15 months.
I do have another level of my house that is not being used, really.
Thanks for the advice on the lawyer, I think thats what I need to do.
I think you already knew what needs to happen, you just needed some support to realize it. It's not an easy decision, nor one that should be made in the heat of the moment. Best of luck with whatever decisions you come to.
Since you do have another level, could you suggest to him that your "separation" take place within the house? Tell him you need space before making that final jump into a costly separation/divorce. Take a time out? Come up with a plan, then follow through. Put it in writing so he can read it. That way it won't turn into an argument and the things you want to say will be said without getting side tracked.
Maybe you could suggest he move into the basement. He can "visit" with the kids on certain evenings for dinner, homework etc. Make it fair. And be prepared to negotiate with him. If you both want to make it work, maybe you could set aside a night a week/month etc that you two can be together to discuss things. Preferably away from the ears in the cornfield (kids). Sounds like you both need to communicate with each other. You need to tell him what you want. Write him letters!!! That way there is no mistake in what you are saying.
Honey, I want you to spend QUALITY time with the kids when I'm out. (Hard to misinterpret what you are saying.)
