Libra x Scorpio: should I let it go?

Hey I'm a libra who has been playing cat and mouse with her Scorpio guy for 4 years.

I was very shy and not very confident when we first met, so I was oblivious to the fact that he liked me and when I began to catch on he would go cold on me. After two years he went a round to study and I messaged him on fb.
He didn't reply to another who liked him in our year, but he always replied to my messages and his friend paid attention to me. I was going through a lot my third year and took the rest of the year off. After about a month of no contact I sent him my cell number to reach me as I was deactivating fb. He never texted me.
A year later, the end of his fourth year, I messaged on fb after I got back on it and he seemed curious about what had happened to me etc. I asked in a dodgy way how he was doing with the ladies and he told me that he had seen someone while I was Mia. I thought this meant he need time to be by himself but told him I had always like him since we had just had a convo about fate and wanted him to know that I was interested in him.
He replied with a "I'm not ready for a relationship" and I was fine, we kept talking even though it was obvious he held a grudge at me for being Mia for a year (his replies were much shorter, but he still replied)
After awhile of me trying to talk to him and him only throwing me a bone when it seemed like I had run out of convo material, I blew up at him after sending him a poem(ugh) and stabbed back, so I stabbed back with pretty words I knew would hurt.
He sent me an invite to like his fb page a few days later (about cycling cross country after graduation for charity).
It had been awhile, but I wished him luck on his trip and told him to take plenty of pictures for me, he said he would.
It's been a month and his trip has already begun, I sent him anoth fb message wishing him luck and telling him I'd seen the pictures so far. He thanked me and wished me a great summer.
That is where we are now. I know he has always let me start the conversations, but he always makes it so I have the option to keep it going.
I know he had/has? Feelings for me but I don't know if he is too caught up in my craziness to still have them. Should I just let him go. Or stick it out and try and be friends? I can't stop thinking about him. I feel like he is mine and that's how it was meant to be.

He studied abroad and he stabbed back with some bitting remarks that hit below the belt.
Sorry about all the typos 🙂

Thanks in advance scorpios!

Sounds like you still aren't confident.

Leave the dude alone.
