Topics…varied.
Money, as you can see from my post. That was very much me believing young adults should either earn their own and if they don't they can't have.
At times we had discussed that I would carry on with ‘my way’ with my own, and he with his.
DP would cover up the fact that he was giving money. Often it would come up in conversation by his DC’s and I would challenge DP everytime, saying I wasn't prepared to be lied to.
Many tough conversations.
I think he felt he was in the middle of my expectations and what his DC’s had always expected.
It changed through tough conversations, including me talking about my views to his DC’s. DP also realised he was being taken for a fool when one of his was borrowing money each month, yet had bought a private number plate for his car!
Being tidy. Rules for all DC’s about the shared areas and their own bedrooms. My children were messy too. New rules were agreed for all.
Helping with household jobs. Mine did, except for one, his didn't. Again, clear conversation, rules and accountability for everyone.
I did find it really hard, initially, to hold his DC’s to account. Mine were always pulled into line. I would remind DP and expect him to do it. That has improved overtime.
Other annoyances. His DC’s and one of mine are avid TV/screen watchers, especially youtube - I hate the constant noise but we compromise. Time for me to be elsewhere in peace or perhaps expectations that we all go out for a walk, or the more active go out.
Planning ahead for the more stressful times worked. I hate family gatherings, including the GP’s where we all sit hour after hour, so I plan a meal out, a walk or a visit to do something so that we avoid the sitting. Being active and busy is easier.
I was a teacher, and maybe that impacts. I find I can be really objective about my own children too and not always feel that DP and his children were always the ones in the wrong.
