I've been with my partner for 9 years when we first got together we started going to music nights together since then we have travelled the UK going to music nights (especially rnb and reagge nights). It's always been out thing and we have always gone together. Next month my partner has been invited out to his friends 40th birthday and it happens to be on the same night as a music event. So I said to him that's fine you go to your thing and I will go to the music event on my own im fine with that. He started saying he didn't want me to go on my own and that I was out of order for going and that he would never do that to me. He then started saying he won't go to his friends birthday and will go to the music event with me instead. I said no your friend has brought tickets for you and it's his birthday. I said I'm fine going to the music event on my own. I haven't mentioned it since but I'm still planning on going to the event but I'm worried about mentioning it again just incase he tells his friend he isn't going to his birthday and then i will feel terrible. Am I wrong for this? He's made me feel im in the wrong.
