My dad has a BBQ every year and they invite about 30 friends altogether. I now have an 8 month old so I was particularly looking forward to it as no one knew I wasn't pregnant last year. We confirmed we were going about 2 months in advance, as soon as we got our invites. But about 2 weeks before the BBQ, DP told me one of his best friends from uni had got engaged and had invited us to their party the same night as the BBQ. Non of us live near each other, and it's about, 45 minutes to my dads and about an hour an a half to this friends. We wouldn't have been able to take baby to engagement party as it was in the evening and so far from home, but could take her to my dads as it was in the day.
When DP asked me if he could go, leaving me at home with baby for the night, I said he can go but I would prefer it if he came with me to my dad's as we had already committed. DP said the engagement arty was for a really close friend of his for a really special occasion, whereas my dad has his BBQ's every year.
None the less, we all went to the BBQ, baby screamed the whole time and we were only there an hour. On the way home I apologised for him missing out on the engagement for that, and he reiterated that the engagement would have meant a lot more to him and he felt he should have gone.
Should I have let him go? I was really glad to have his support at the BBQ with baby screaming.
Who was being unreasonable?
