Should you tell someone that the reason you keep refusing to hangout is because you have been battling depression?

This guy messaged me on Facebook and we talked a few times on the phone. I am interested in him and like his conversations. He even sent me flowers to my job although we haven’t met. He invited me to multiple events and offered to fly out to meet me, offered to fly me out to meet him, invited me to multiple public events like a comedy show, a party, a video shoot, and multiple other things. But everytime he asks to meet I just lose my desire to get out and do it. All I do is work and come home. I cry every night. I try to pray for a healthy mind. I’m sad all the time lately. Sometimes I talk to him because even though I know just talking on the phone is boring he is really inspiring. He told me today after I turned down his request to come down to my city to take me on a date that he was getting discouraged and he wouldn’t keep trying with me. I vaguely told him that I was dealing with a lot of personal stuff and that I didn’t want to hang out because I wasn’t in the right headspace. He told me he would have to call me back but hasn’t yet. I understand if he doesn’t want to be friends anymore and I don’t blame him. But I just wish I had the right words to explain what’s going on with me
