am I being an ass whole?

I feel like a jerk but I can't help how I feel. This is my 4th round of clomid. I have been on these crazy hormonal drugs for months. That make me crazy. Had all kinds of testing done that's not pleasant and next month if this doesn't work we are moving on to IUI. Literally every month since we have started clomid. My husband has not been able to perform at least 2 of the times we try. We are suppose to have times sex 4 times during my fertile week. This month was the highest chance of pregnancy. I feel like this isn't normal. And every time he blames it on something else not in the mood tired or not awake. This time he said I moved funny and he just pulled out. I didn't do anything different than I would normally. I'm just frustrated. His count is extremely high, but none of that matters if he can't have sex when we need to
