I've had a look at some of the other threads on here before posting and am pretty sure I'm going to get some sound advice.
My partner has a beautiful 2 year old daughter from a brief relationship (four months), all over and done with before he met me. I like spending time with her and we seem to get on well, although my experience of kids is pretty limited. It's not her, it's her mum who I am struggling with. I want to be supportive of my partner but feel as though I am losing myself, taking my holiday time to spend with him and his daughter, while her mum has time to herself with her latest man. She's making plans for a ski-ing trip next year and I only find out about this over drinks with friends when my partner tells me he's taking a week off to be with his daughter. We don't get much time together as it is and I can feel I am starting to become resentful of the situation. Perhaps this says something about the relationship I have with my partner, I don't know.
How do I say something without sounding like a spoilt brat myself? I accept that I am the adult and children come first. It's honestly not the little one, I just feel it's so unfair that her mum gets what she wants. I feel as though my attitude towards her mum is clouding my relationship with my partner, possibly the child too, and I don't want that.
Perhaps I am just not ready to be with someone who has kids.
