My daughter in law was ok until she married my son after being with him for 14 years by that time, and having 2 children. She seemed to ramp up her possessiveness each year...yet no one was trying to take him away! She certainly knew she held the ace card.
Before that I helped all I could, going over to play with the GC once a week [all approved by her], picking them up from nursery, babysitting, having one of them for weekends to give them a bread, taking them out for most of the day in school hols etc. etc. I never interfered.
Then I started to feel unwelcome, subtle differences, I asked if everything was ok...yes it was. I got digs and scoffing about my age, snorts if I said what I was doing at weekends etc...just ridiculing me in general. It was making me unhappy and I did not know what was going on, just that I wasn't needed in the same way as when the GC were smaller.
She then posted something on the internet inferring poor parenting and interfering with GC...basically a huge lack of respect for me and my life. She thought I wouldn't see it. I did. I was gutted, it was nasty. Just DIL showing off to her friends. [It's a long story, much more to this I would be here all night. That was the last straw for me].
My son was furious with her. I asked for an apology. A text would have done, let alone a visit [we live quite near, a walk away]...3 years on she hasn't and won't. My son comes to me now and brings the GC, he won't allow me to lose contact. My other son and other DIL are wary of her, are polite but not impressed.
I now longer go to their house. It's best this way. The thought of seeing her and her betrayal literally makes me feel nauseous. She's told me in the past it is 'her' house!
She has her own problems and demons yet I have been the one in the firing line.
