Husband thinks I’m being unreasonable

My FET is in two days and husband just told me he has a very important meeting so he’ll drop me off home from the clinic and then go to work. He’ll come home after 6-8 hours and I’m upset. I asked him to do wfh and stay with me but he said ‘what’s the big deal he’s not going to be out having fun and it’s only after the transfer’. Maybe it’s the medication, maybe I am unreasonable but I feel like this isn’t something I should even have to ask. For some context we live in a foreign country where we are each others only family and this time around I haven’t told any friends. So he’s my only support. Please advise. I’ll really try to be as reasonable as I can be right now. Maybe he feels this way because it’s our 4th try, the first three all resulted in losses whereas I think I need more support now. I don’t know…

EDIT: Wow! I did not expect so many responses. I really appreciate everyone giving their POV and do understand this could be the meds talking or a personal preference situation since everybody is on their own journey. Just want to say thank you to everyone on the forum and sorry if any negativity has arisen because of this. Love and hugs to y’all.
