Being intimate with SO

Well today was peak day for ovulation and for some reason my SO just didn't want to baby dance at all and does not want to, I'm confused, we've wanted for so long to have a baby we committed at the start of this first month of ttc, and now the most important time is here and he doesn't want to, I'm unsure how to feel so I'm just not talking right now, it's hard to be told yes i want a baby and we are ready but then no effort! I'm confused. Any advice?
