Is it deceiving?

DH and I are actively TTC. He is fully agreeing with it, the problem is he just 'wants it to happen' without actually trying. I tried bringing up OPKs and he acted like he didn't want to hear about it, he didn't want to know if I was using them. I bought some preseed, but I feel like he's not gonna want to know about that either. Is it deceitful for me to use it to increase our chances without telling him?
