It just shows there never was a miscarriage
The series of unfortunate events were that she got dumped after a very short fling. A relationship she forced to be too serious, too quickly, instead of letting it blossom organically. She loves the idea of being in a relationship and being able to show that off. In reality she's a very difficult person to be around and it was nothing more than a short fling for him.
Were lessons learned? Probably not. If she met a man tomorrow would she force him to be part of fake public happiness. Force him to quickly become part of her household and H's life.... absolutely she would. As a single parent it is absolutely possible to date for months, years even without constantly forcing new relationships on your poor child. There was no safeguarding of H with D1 or D2. The brief shack up after her marriage was before my time so I can't comment on that one.
As for the illness over Christmas and new year. It was a cough and a cold the attention seeking wh*re! Just because Dr wendy gives a diagnosis doesn't make it any more likely than Aimee never using a filter
Is she building up to a mental health crisis as we haven't seen one since the DVLA investigation? or maybe she's going to catch the worse head cold ever from H? She hasn't had a period for a couple of days either......
