AIO my gaming friend/guy who tried to date me, borrowed money from me and won’t pay me back

For those who don’t want to read all the screenshots, I’ll sum it up as best I can here. I(26F)met this guy(forgot his age but I think I’m older) online on the game Fortnite. We have a gaming group chat with a bunch of people in it, including his brother and his brother introduced us to him. He would always play the game with me and we would talk a little bit sometimes on Snapchat at one point we were talking daily and he let it be known that he was interested in me and wanted to pursue me, but I did not feel the same because he had no time for a relationship and some of his behavior was very odd.

Like he would never call or if I called, he would not answer because he was trying not to disturb his sister apparently but I did not understand that theory. Both of them are grown, and both of them are sleeping in separate rooms and she would constantly be on the phone in the background in his voice notes. So that pursuit did not go anywhere because it smelled fishy so we still stayed in contact and he was constantly flirting, but I let it be known that I was just a friend and we lost contact for a couple months and he reached out to me asking for money in January and I had not heard from him since probably October.

He gave me this long, drawn out sob story about a child being locked out in the cold with him, which is how he got the money from me, unfortunately I did not save the messages when he originally asked me for money, but once he started to begin the shady behavior, I started saving the messages. He even turned on the option to delete messages once you send them on Snapchat when he noticed I was saving all the messages. I gave him the money because I thought we were friends and I could trust him, and because my heart went out to his situation, but in the end, his true colors were revealed and he turned out to be a scammer and a little disgusting thief.

I know there’s gonna be some weird person in the comments saying “it’s just 15 dollars” but the amount is irrelevant, stealing is wrong whether it be $15 or $15,000. It’s the fact that I knew you for as long as I knew you and we had the type of relationship/friendship that we had and you throw all that away over $15. It was the principal and disrespect for me. it had nothing to do with the money and even if it was strictly about the money I have that right as well because at the end of the day it is mine and it was owed to me. But in yalls opinion do you think I overreacted?
