I don' think your being unreasonable at all!

I had to kick my DH out that night at 10pm so he could go home and get some sleep! he was aloud to stay but i thought at least one of us should get some sleep so he reluctantly went home and was back at 6am the next morning and stayed the night for the rest of the 4nights i was in hospital!

Surley ur partner can miss one poker night! its a very special event having your 1st bub and one that u will never repeat again! i hope he comes around and spends the quality time with you and his bubba!
