Should I continue with the treatment?

Me and my husband have been trying to conceive for two years

it’s come down to our UI as of recently and he can’t go to any of the appointments because he’s always at work I’ve been doing all the appointments for the past couple months by myself

he was asked to complete an online course for the IUI and he told me that it’s stupid and he doesn’t want to watch the videos all that matters is that I get pregnant and he doesn’t need to know how it happens

that of course upset me edit and ended in a big argument so now I’m wondering if I should continue the treatment if he’s going to be like this I feel like it’s a foreshadowing of how things are going to Be

Help please?
