I started dating my ex-partner 3 years ago and he has 5 children from his first marriage. A few of the kids I got along with very well and the others took a dislike to me. I accepted this and did not fight it as it was his kid's right to like who they like. However, I have found his relationship with his kids quite hard to understand as often they have openly told their dad that he is only good when they are in a crisis and only rely on him when something goes wrong.
As someone who is childless and has a different view of how I would treat my own parents, I found this hard to deal with. I wanted to be respectful and support him when this happened but often found his kids took advantage of his time and accessibility. When the kids would visit, they would treat his house like a tip and expect him to pick up the mess and he would moan about said mess and never call them out on it. Just for clarification the kids ages range between 21-35 so I was under the illusion they could clean up after themselves.
The relationship has come to an end recently as I found that when my ex's kids suddenly needed their dad in a moment of crisis, he would immediately stop what he was doing with me i.e we would be out for a drink or watching tv at one of our houses and our plans would have to stop on account of one of the kids saying they needed him to come home/be on the phone/ drop future plans for them. I totally respect as a parent you would do anything for your kids, even though I am not a parent I get that your kids needs come first but I am confused as to why I feel I am 'left behind' if you will? I suppose I am asking, did I expect too much and was I being selfish expecting to be on equal footing?
I am quite hurt that he has ended the relationship as I love him greatly but I have often felt 'second best' and somewhat disrespected when he would just up and leave me behind when his kids decided to appear out of nowhere. I have been blaming myself recently as I feel as I'm not a parent I may not understand and therefore I am being selfish by having these feelings.
Any thoughts/opinions/hard truths would be appreciated.
