Discovering red flags in newer friendship

Last Friday, I had a get together at my place with some friends of mine and for the most part had a great time.   Of the people who came was a newer friend of mine and happened to see several red flags.  🚩.

1. When he showed up, he didn't seem like he was that excited to be there
2. He told me that he was tired
3. He kept asking me when we were going to open gifts because he got me one
4. When I asked him about a friend of his, he told me that he did not want to talk about it and not to ask him about her anymore because they fell out
5. He didn't really interact with anyone
6. After he left before everyone, he sent me a very rude text in which in criticized me by not only giving unsolicited advice but also told me that I had to change
7. He told me that he was only telling me this because he is my friend and cared about me
8. During an exchange in text messages, I attempted to set boundaries

-He minimized what I said with "Happy Birthday and Goodnight."

-He also wanted to keep having the last say

-He gave me a fake apology

-He wanted to have the last say and argue back 

At that point, I didn't even say goodnight, I just stopped responding and then unfriended him and deleted his contact information.

8. Then after I unfriended him, I noticed that he and this woman, who he said that he fell out were still friends on FB.   

-Though I don't want to gossip, I do question him on what he told me. 🚩
