Hi Quart, you asked me to drop by your thread and give my POV on it. First of all, your W knew she what she was doing when she asked you to move out to give her space.....and you left under false assumptions b/c you thought it was to be a "short separation" and the next thing you knew...she was asking for a D. On those grounds alone, you should be able to move back into your home.
This is how she'll see it. She will immediately cut off your financial support from her. So, unless you can support yourself or the courts force her to give spousal support (and you don't know the time frame for that), you will be up a creek. Logically, that is what you need to look at before going any further.
A WAW must see her LBH standing tall & strong regardless of what she throws at him. If you are dependent upon her for your livelihood, it could influence her vision of that. Don't misunderstand what I'm saying here. She was not mature enough to ungo what was needed to be the breadwinner while her H went through school in order to have a higher standard of living later. That was obvious when she wanted to return home after your first struggles getting into the college. As time passed, her resentment grew and grew until it led her into other things.
The only reason she was nice the other day was b/c she thought you were politely letting her lead you around by the nose. The minute you stop cooperating like she wants, the minute she stops with the hugs & kisses.
I agree with the others, you must have a plan beyond moving back into the home. If you move back...then the real war begins. I think the women you talked with realized how angry they would be if their H's moved back uninvited. (But again, it was under false pretenses.)
You are wise in getting information before jumping into something you are not prepared for. I think you may have to make some very tough decisions about your school. You have gone through a lot to lose it now, but if you have to work in order to survive....then that is what you have to do. If the classes required so many hours, what do the other students do who have families? Does your scholarship have an allowance for living expenses?
It is not about what you feel should work in your M. It is about doing the work that gets the right results. Do what works!
