LDR, please help!

He said he was busy with a paper but Eh it’s kinda hard to believe since I saw him online and he sounded kinda neutral and didn’t say anything about the memory: / I texted him back encouraging him cause he seemed kinda down about Halloween and he replied with a thank you with a smiley face. I’m texted back again positive and everything and he hasn’t said anything in 2 hours. I’m really trying to be confident and positive and interesting but I can’t tell if it’s working for him. I really would love to get back together but idk if I’m doing things right

Here’s an update for my situation:

I sent the message I said above and she replied with “thanks! I can’t go anymore but means a lot!!”

I think that’s a good response but I still have a feeling she’s just being friendly
