Background - I am divorced and have ds11.
I have been with current DP for nearly 3 years. We don't live together.
DP has 4 children from his previous relationship. He earns an OK salary (around 50k) but obviously having 4 children is expensive and the majority of his money goes on his children (rightly so).
I earn less than DP (35k) but I have worked hard to get where I am today and had years of being skint, paying childcare costs and similar. Now I have more disposable income DS and I like to go on holidays abroad and weekends away.
DP thinks I'm being unfair by doing this as he can't afford to take his DC abroad. We go on days out all together and spend time together but DS and I also go on holiday on our own. My viewpoint is he chose to have 4 children and not many people can afford to take 4 children abroad! I can't afford to pay for all his DC to go.
AIBU? It's a bit of a bone of contention between us as we are thinking about moving in together, but I don't think it's fair that my DS should miss out on things because he can't afford to do them with his children. I'm hesitant about living together to be honest.
