DH wants to stop TTC? Low sex drive!?

Anais
DH told me today he wants to stop TTC. We've been TTC for 8 months now and he wants to quit because he said his sex drive is low (because of work stress) and he doesn't want the added stress if "having to have sex." I'm trying really hard to be understanding because I appreciate him being honest with me and I never want him to have sex with me, let alone have another child if he's too stressed... But I'm having trouble holding back my tears and feeling as understanding as I'm saying I am. Has anyone else gone through this?? It's so confusing because he's wants baby #2 for two years but I wasn't ready till 8 months ago and now he doesn't want to any more??! I'm so confused and heartbroken. I feel like it's more about having sex with me then it is about another baby.
