So, me and my DP have been having some difficulties in the bedroom recently, however he's now been put on medication and things are going great 
So, it was his birthday this week and today I took him to one of his favourite places, payed for VIP treatment etc. Cost me my weeks wages nearly but never mind! Well on the way there we decided (thus being my suggestion by the way) that on our return we would stop by at the local fancy dress shop and pick up some costumes for tonight ;).
Cutting long story short, DP loved his day out and was beaming from ear to ear at the end. So anyway afterwards we get into the car and begin driving home (me feeling all excited about costumes) when DP says to me, "great day babe are we ready to go home?" to which I replied "Oh, isn't there anywhere else we need to go?" the answer, "No, don't think so," and drove us all the way home.
So now I feel really annoyed. I gave my wages and my time for him today doing something I hated just to please him. I didn't want to "remind" him of the shop because I thought if it was important to him he would have remembered, why should I have to keep telling him. I suggested it and he knew how excited I was . Now I feel down and a bit cheated. Aibu? Would you have felt the same?
