Bananas - I am a long term poster, but mainly lurker
and have long read your posts and felt they resonated a lot with my life.
I am sad you are splitting up with your partner but also a bit pleased because you are getting out of the mess he has created.
I have always really wanted to be a "family" with DP, my son and his kids and I have complained many times about feeling like a lodger in my own home. You can decorate it as much as you like, but if the people in it, treat you as an outsider or someone who isn't part of things, then you will never feel like it's your home.
In answer to your points;
- feeling that your opinions are worth less than others.
Being told that you are "making a fuss over nothing" when you try and talk about family rules or pointing out injustices in the family.
- feeling that the first family is dominant.
For years I had the constant conversations from the kids about all the things they had done as a first family. We have taken them to lots of lovely places, they have never reminisced about our good times. They are instantly forgotten. It's very hurtful.
- step children who are allowed to be rude or ignore you.
My eldest DSD would walk into my home and ignore me and walk straight to the fridge. I tried to talk to my DP about it and was told I was "making a fuss over nothing". They would insist on sitting with us all evening but wouldn't make or be involved in any of our conversations. It was like they didn't want us to have any privacy but didn't want to be with us either. DP refused to do anything about it and we went a long time without ever really having alone time. I came very close to leaving over that.
- EW being intrusive, bitter.
EX wife has very little to do with her children and yet I am still doing all the donkey work for them along with DP. She has never worked and has tried to dictate all sorts of things. DP ended up in court, which despite not being supported in my wishes, I supported him with.
We have all sorts of arrangements over the years including one full time and losing contact with one at the same time. All contact was scheduled to please Ex wife or DP despite me and my DS having the consequences of their actions as much as them.
- having step children every weekend.
I agree - if a parent doesn't ever want the quality time with the children, something is wrong.
- DSCs allowed choice over seeing a parent when too young to make that choice
This was the one thing that DP was supportive of and insisted that DSD see her Mum albeit not for the length of time that was agreed. He only did this though because he wanted a bargaining chip so he could see the child that went no contact.
- DSCs excluding SMs, through insisting they see DPs without them always, excluding SMs from big events.
Not so much me, but my son. DSD1 wedding last year was paid for by us (with 6 weeks notice!) and yet she didn't include my son in the wedding party until the last moment, by which time the upset had already been caused.
- of course... Disney Dads and entitled kids! Indulgence with money and such because of Dad guilt.
Cars, weddings, 5k school holidays, guarantor for a 19 year old that wanted to live with boyfriend rather than wait. Often DP wasn't even "asked" just "told".
Kids are all much older and when they are at uni (which actually is only about 5 months per year!) things are a lot easier but deep down I know I should leave. We are on a completely different page with regards to parenting. He says a lot of things about manners, respect, chores, encouraging work, discipline to other people but doesn't actually expect one iota from his kids whilst simultaneously trying to tell me how my own son is lacking in all of the above.
