Every time DSD is not the centre of my plans I pay a very high price, and it's getting me down 
DSD and DP live with his parents, I live with my DC and we are looking for a house together.
DSD and DP stayed at mine last night. DP isn't well but said DSD could chill with him today. DSD wanted to hang out with me all day, but I explained that I had a few plans. My old sch friend had texted to say she is back in the UK and would like to meet in our home town today, and I explained that any other plans would fit around this meeting. DP suggested friend and I take DSD out for food, but I said that my friend had expressly said it would be just she and I for once, which means we could really catch up. I made a few other plans with DSD by way of an apology, although I do not feel any apology should be needed. Overnight DP said I was nasty to her
I had also asked her not to stretch my old baby blanket as it means a lot to me.
Today I'm told I clearly resent DSD and find her to be an inconvenience
that's not the case at all! She is lovely, although she has high expectations of me, but they will lower in time!
Recently DSD was invited to an event by her maternal family, DP and I were also invited. While it was nicer
