Remember, just ignore the mystery phone calls and other stuff, unless it is actually threatening you, if it is threatening, then get in touch with the police.
I would really keep absolutely quiet for a few days, no phone calls at all. Wouldn't that be a 180 for you? Wouldn't it make your H notice?? Please, really consider it. It seems that what annoys him most about you at this point is your constant clinging and 'always having something' to go on about. Give him 'NOTHING' for a change!
Meanwhile, get to feeling better about yourself - you are a WRITER , remember? A good mother? A strong woman!
You can do it!
