First fertility appointment excitement

I have my first fertility appointment next Wednesday that I’m due to attend with my partner, obviously after trying for our rainbow for so long I’m so excited to attend and the one person I should be able to share this excitement with is my partner however i feel myself having to hold back as he doesn’t seem excited and tries to brush any conversation of it off which makes me feel like he doesn’t want this despite him saying he does. I also feel a sperm analysis before attending this appointment would be beneficial and save time so we could discuss the findings at the appointment however again when I’ve mentioned this in the past it’s been brushed off and I’ve been to nervous to bring it up again. Was anyone else’s partners like this and what did you do?
