Am I overthinking?

Long story short….
we had to buy an Rx for something, I asked him to help split the cost since it was expensive. He agreed. I thought about it and felt guilty for asking and told him to not worry about it, I’ll take care of it. He was like ok cool, I’ll send it when I can.

few days go buy, we got into an argument and he ended up leaving my house abruptly. I was done at this point, ready to move on, and just let that situation be. I told him to leave me alone and block my number. He did, well I get a notification mid week (after we hadn’t talked for a few days) and he sent me the money and unblocked my number and then admitted to me he unblocked my number to Zelle me the money and then admitted that he did it in hopes I would respond to the money he sent me even though I asked him not to.
Someone told me he’s just using me for sex…but logically if things end between you and a person, and they asked you to not worry about sending them money and to leave them alone it you would send them the money and reblock their number…or just not even send them the money and move on entirely.

call my crazy but that’s a little excessive for someone who just wants “sex”. Regardless if you want to continue with that person or not usually you wipe your hands clean of the situation and leave them alone when you ask them to.. and move on also…
(we haven’t had sex since then just an FYI)

I don’t know what to think anymore at this point 🤦‍♀️

Update: I’ve always been told guys speak through their actions and his actions to me lead me to believe he wasn’t over the situation yet and maybe there were still some unresolved feelings on his part so he did a half butt attempt to get my attention
