Don't worry I have done the exact same thing to my DH! I lost it and accused him of doing it on purpose as he didn't really want to have a baby (all in my mind of course he wants one just as bad as I do.) Easier said than done but try and not beat yourself up over it. TTC is very stressfull when it doesn't happen easily and we aren't super human so of course we are going to crack from time to time. If it makes you feel better after screaming at my poor DH and then apologizing profusely I cracked it again the day my AF came and told him it was all his fault because he didn't bd when I said we had to. Nice wife I am hey. Luckily he forgave me though as he knows it's not how I really feel.
