Husband having issues

Hey ladies, I am writing this question because I am desperate and need to know if anyone has been through this and if things get better or not.

Ok so my husband and I have been together for a total of 8 years. We’ve been married for 3 years and have a handsome 11 month old. My husband and I were intimate quite often before having my son and after we did it but not as much as I wanted to. In August, we decided we wanted to start slowly trying for a second and we tried to have sex well... he wasn’t able to stay hard. So we tried again few weeks later and yep still same issue. I didn’t know what to do besides just cry my eyes out because I thought it was me. He swears and says it’s not me and that he will stop drinking and go to the doctors and he even told me he hardly masturbates. Since the pandemic, he is always home and hardly goes out anywhere. He works from home. I love this man so much and I just want it to go back to normal. Has anyone been through this? Is ED common? He’s only 32 and idk what else to think? I’ve tried bringing it up a couple of times but now he just gets upset. I told him I need him to show me or prove it to me it’s not me that’s making this change. I feel horrible, I’m starting to hate my body and feel insecure 😔.

Please ladies, help me out. I want to stay positive so please no negative comments.
