Do people reconnect?

A good friend and I hooked up a few months ago. He ended it after 2 weeks of talking saying he just wants to stay good friends and it’s been hard. We talk here and there, I send him funny memes and he’ll like some. Last night, I hung out with some of our other friends. I told them what happened and they gave me really good advice. I’ve been so worried that guy and I won’t remain good friends and that when he’s home he won’t want to hang like we used to. My friends all told me that they’re pretty sure he’ll still invite me to hang. He’s also started talking to a girl a few weeks after we ended things, and one of my guy friends told me that it’s honestly for the better because LDRs are hard. He told me to let him have his little fun from across the country now and he’s pretty positive things could possibly pick up again in the future. They also said that girl he’s talking to is prob just like a lil tinder thing because he’s bored. This guy friend lived with him for a while so he knows EVERYTHING about him and he even told me that this guy has liked me the instant he saw me 5 years ago. I want to believe them but I overthink SO much. But they literally all confirmed to me things will most likely go back to normal. I send that guy memes here and there and he’ll like them. It’s pretty much gone back to normal and I obviously want to stay in touch as a friend but I don’t want to be annoying and push him away. Do friends fall back in love down the line? Am I just overthinking this whole “staying good friends” thing?
