I've been feeling down lately and then this happens...?

I have depression. I've had it since I was 12 years old. It usually comes and goes, some days I will feel super down and other days I feel okay and am able to function and do fun things. Flash forward to about June 2016. I start talking to this really nice guy, super sweet, super cute. We have been talking up to this day (about 5 months) well today we were talking and I was curious so I asked him if we were ever going to date. His response, "I don't date long distance." I don't understand how anyone could talk for 5 months and basically act like they're dating and then he respond with that. I opened up to him and told him everything, he told me personal things as well. I'm in tears just writing this because it's like he took my heart and shattered it beyond repair. I don't know if I should end it all or fight through this. I'm tired of fighting...
