Confusing communication with ex

Mariah

My ex and I broke up in April. He said God wanted him to be single for a while but he wants to stay friends. Fine. I can do that. (Also he tried to VIDEO CHAT ME on FB Messenger ONE HOUR after dumping me)

Did NC until my birthday, kinda try to talk a bit after that. Sometimes, he’ll reply right away. For example, I messaged him asking if I could give his ticket to a concert we’d wanted to see to my friend. Instant response and talked for 3 hours straight. He’s on Snapchat so infrequently that the times we do snap have made him on my “best friends” list(he’s also stalked me on there since the break up). Yet, I sent him a pic of one of my students in a Star Wars (his fave) costume and he viewed it right away but never responded.

His sister(my bff) says he NEVER EVEN WANTED TO BREAK UP, and my friends at work(non Christians) think that he’s still into me. And I just have this feeling it’ll work out... but I’m confused. Should I keep trying? He’s the one who wanted to stay friends. Or just do another NC?
