<human>: Summarize the given text in a few sentences.

Hello Reddit! This is my first post so I'm a bit unfamiliar with guidelines. 

I'm currently studying abroad for the summer, and met this guy a month ago. We went on a few dates, and in the first few dates he was already asking if he could visit me where I lived since he had the funds to visit me 3-4 times a year. The last time I saw him was when he took care of me for the entire night when I was sick, but couldn't make it to the hospital. He was also really worried and wanted to take me to the hospital himself the night before, calling me and my friends multiple times. He ghosted me immediately after. This was my first relationship, and he knew this, so I confronted him about ghosting me, which he denied, and he strung the conversation along for a week. He hasn't talked to me in a week and I know he's with another girl, but since my program is ending, I wanted to thank him for being my first kiss and to wish him luck going forward. I guess I really wanted to have him as a friend since he was a really interesting person to talk to. Should I send him the thank you message before I leave?
<bot>: guy ghosted me after being obsessed for the first dates and is seeing someone else, but I want to send a thank you message since my summer program is ending, and he's my first.
