No my relationship hasn't ended.
My dh previous relationship did end before me, if you asked her she would probably say it was because of my ss. It wasn't. It was because deep down she didn't want to be in a relationship with someone who had kids. She didn't want to "compete" for her partners attention, time or money.
Personally despite having a blended family myself for heading towards 20 years and kids together, I think in general they are some of the most toxic and dysfunctional family set up children can be exposed to.
We consider ours fairly successful, that doesn't blind us to the fact the reality is the older two had much harder life's overall than the younger two. We did family counselling when one of them was a teen. To be honest its pretty hard sitting in a room trying to defend against there feelings. When if you dig deep and are truly honest hold alot of truth. They have more difficult lives, with people they may never like, in situations they didn't choose because of who their parents want to sleep with.
We have so many blended families around us be it family or friends. Both our older kids are parts of blended families on the other side.
And honestly there is probably only one other I think works anyway well. The rest are different combinations of fcked up that the parents never mind the step parents should have left long ago.
The competition, jealously, constant need to prove who is more important in the pecking order, which in my experience is usually a SM, with either her or her kids. The cinderalla effect is 100% real in my social circles, with weak as fck men who should be the ones ending the relationship, never mind the SP.
Men don't struggle as much being a SP not because of lack of boundaries, the don't struggle as much as SM I think because they tend not to hold as deep routed emotional insecurities. The most toxic of SP relationships in between girls and SM. I despise with passion the term mini wife syndrome. It actually makes me gag because underneath it is an grown woman who sees the relationship as an equal competition. Not the child who is just trying to hold on to some form of attachment to their parent.
It takes massive amounts of emotional regulation, having very little of your own unhealed trauma to deal with, empathy, ability to compromise the list is endless to have even a half way functioning blended family unit.
Don't even get me started on the tripe that is rolled out about adults needs, children's wants retric.
And also I don't align to the school of thought that just because someone apologises you need to accept it and move on. It isn't something I'm teaching my kids, especially my daughters. So it's for the person who is being apologised to decide if they want the relationship to remain on the terms it was.
