Ghosted :/

I was in a relationship for almost a couple of months. We were exclusively dating. We were so attracted physically, emotionally and intellectually to each other. When I started bringing up the idea of becoming intimate after six dates, he kept saying that he’s the type of guy who takes it slow. Eventually he agreed to do it sooner rather than later. He started telling me that, for him, it will take 1-2 hours of lovemaking. I thought, wow, that’s going to be great. And then that night came that we were supposed to be intimate like we agreed to. I noticed that he could not get an erection even though I tried to help him. He has diabetes and so that goes hand-in-hand with ED. I guess the 1-2 hours of lovemaking he was telling me about meant that it can take that long for him to complete the act. I wish he was more honest with me about this issue.
He ghosted me after that night. It’s been two weeks. I’m hurt but I am moving on. Looking back, I know this will be a big issue in our relationship but I wish he gave me a chance to work around it. One part of me wants him back. The other part of me knows that this can be a big problem later on. I am almost embarrassed asking this question but I would appreciate some input. Is it worth saving this relationship? He’s been divorced for 15 years. Not sure if that means something.
Thank you.
