My ex boyfriend's best friend got me a sweet bday gift, is that weird?

Well last year my ex was supposed to get me a necklace that I wanted and he never did for my bday. So this year his best friend bought me the same necklace from a popular anime I really like. Apparently he asked my ex if it would be weird and he said no. The best friend was supposed to hang out with us but he said he was tired so he stopped by to give me the gift and left. He said he saw it and thought of me and knew I'd like it.

The best friend also kept asking me if "I'm ok" which was strange because I didn't do anything weird.

My ex has said before that he thinks the best friend might like me. He said he treats me different than other girls and he talks/asks about me when I'm not there. He's flirted with me in the past, like laying his head on my lap or shoulder, or saying I look cute over and over, he touched me a lot to get my attention like on my arms/thigh, and we also have a lot in common it's actually pretty uncanny he tends to still be shocked that I'm into anime and stuff lol

But yea, does anyone think it's a little weird? Also my ex didn't get me anything at all (yet but I doubt it) but his best friend did. Opinions?
