I thought I would post this, Eden, because this is just some of the things I would be thinking in your husband's situation. (pardon the use of "husband", it is the most convenient term of reference). That is, losing my job, rekindled (possibly) romance with my ex, and all the other things you have describe:
Life sucks, lose my job just as Eden and I are... whatever this is... why would she want me? How will I provide for my family? AAAAAHHH!!!!!!! How am I going to find another job? What if I asked Eden if I could move in, that we aren't paying for two households? What if she says no? What if she doesn't want to, does that mean she doesn't want me, but what if she says yes, does that mean she does, or that she is taking pity, and how will it work, where will I sleep, what will I do with my stuff, what will happen to my routine and life, I'm so confused, I better not say anything about it. I want to be with her, I still love her, at least I think what I feel is love but it doesn't seem like this is what other people when they talk about love, and its scary and if I admit I'm afraid of what will happen, she might not like it, I'm not ready to talk about all that, I don't think, maybe if she brings it up first, but she probably won't, and in any case, I just lost my job, why would she want me anyway...[start at the beginning]
Around and around. Of course, there would be personal details in there and detours down different trains of thought, but it would eventually come back to the beginning again.
When I get caught in these sort of loops, I'm just a mess. Looking back at it afterward, I find it mildly amusing that I was so wrapped around the axle about things that usually turn out to be relatively simple to resolve.
