Husband and TTC

My husband is driving me nuts. He says he wants to try for kids but I struggle to get him to have sex with me. Every time it comes up he just says he’s way to tired after work or won’t wake up before work to have sex. It’s really starting to get old to be honest. I’ve tried to explain my frustration about it but it doesn’t seem to click. We got pregnant in May but that ended in an ectopic pregnancy in June. I’ve tried to explain that my chances of getting pregnant got a lot harder because I lost my left tube because of it but he just doesn’t seem to get it. Ugh I’m sorry to vent but I’m lost. Any ideas on how I can get my husband more excited about all of this??
