After much debate and discussion I told DH just to cancel it as he's just too wound up about it.
We don't want any more kids, I certainly don't and I offered to be sterilised but he doesn't want that either. He says that the knowledge that we can still reproduce if we want to is a big psychological thing for him, especially if (heaven forbid) something happened to the kids. I accept this.
But then things seem to get all contradictory. What I can't understand is how much he goes on about how important the kids are to him and how spending quality time with them is the most important thing but he never actually walks his talk. He is a great dad but he works long hours, sometimes more at home and at weekends and is often away abroad. He has now been requested to attend a meeting which will mean that he misses DS's birthday. He's already missed DD's birthday for the same reasons. There are other milestones he has missed and I just don't get it!!! Could someone please help me understand what is going on in his head. I feel like we all come second best. There is never a time when I feel he puts us before his work, ever. I can put up with the long hours and him working away but he never compromises. Every family holiday we have had has been interupted with him taking a work call.
