Is it selfish to feel sad 😞

I️ live in Austin, TX with my 6 year old son. My boyfriend lives about three hours from me. For Christmas, my son is supposed to go to Virginia where his dad lives. This will be our first holiday apart since he’s been born. I’m so incredibly sad over it but it’s pretty much set. My boyfriend is in TX bc he’s in the Air Force but his family is in Missouri.

He was supposed to come stay with me the 24th & I️ was going to take him to the airport the 25th in the afternoon so he can go home. He kept saying that even tho I’ll be sad without my son, I️ was going to get to wake up to him on Christmas Day. Well he found out that he could fly for the same price and leave on the 23rd & so he went ahead and booked that ticket. He hasn’t seen his family since last Christmas and his mom still thinks he’s not coming until the 25th so he’s going to surprise them.

I️ understand he misses his family and that’s two extra days he’s going to get to be with them but I’m upset that I’m now going to be waking up alone on Christmas bc my son leaves the 23rd too.

I️s it selfish of me to wish he had stuck to his original plan to be with me on Christmas?? I️ want to be happy for him bc I️ know he’s excited but I’m afraid I’ll cry when I️ take him to the airport & make him feel bad.
