6 months, no sex

My husband went through something over 6 months ago. It caused him a lot of pain and he tried to kill himself and I found and saved him. He went inpatient and is in trauma therapy. We haven't had sex for 6 months. I've been really horny but didn't want to pressure my husband. Especially when he's going through something so bad. He has been doing better the last month. He's had some epiphanies in therapy. He seems to be getting back to being happy. Should I attempt to initiate sex?
