My wife has been out of the house for a week now. Last nigh

My wife has been out of the house for a week now. Last night she calls to inform me that she thinks she's pregnant and she'll take a test today. Then she goes on to tell me that it will change nothing between her and I, but she would want to come home during the pregnancy and a couple of months after the birth she wants to leave again. Still leaving me with the kids. What kind of person does this? I thought I would be elated if we decided to have a third child but all I am is more scared than ever. What I'm going through now with my other 2 children is hard enough and the thought of being a single parent with a newborn is almost too much to bear. What do I do? What do I say to her? How do I handle this situation? She has a mental illness and has been erratically manic the past couple of months. I don't know that I can live like this for another year. I know it's best that she is in the house during the pregnancy so I can make sure she is taking care of herself but the unwillingness to work on us even a little will just make the tension unbearable. I thought I was lost before but now I don't see any light at the end of the tunnel. I feel hopeless. I just don't know what to do but I do know that I can't take much more. I've never felt so weak and alone

Any news one way or another if she is? Does she have any contact now with her children?

@lostdad802 I’m kind of at a loss for words. I guess when it comes right down to it; she is coming up with theoretical information. You are dealing with realities. You are hurting, you have 2 children, and those are known things. I would hold off on any kind of planning, or worrying about her until you know what you are dealing with.

Test positive. I don't even know what to say at this point

If your wife's behavior has been erratic and manic than is it possible that you are not the father? Maybe you should consider asking for a paternity test.

Wow, now I really don't know what to say. Have you spoken to someone locally? An attorney,a counselor?
