Did my Scorpio friend ever had feelings for me?

So I ve been his friend since a year now. He had 2 relationships in past. He is single.

Intially he was so gentle and humble towards me but then slowly he started changing. At present I noticed he ignores my text even if I ask help or reply in one word.

These days his behaviour is confusing me. Since long I had noticed lots of signs that made me doubt if he likes me.

-he told me his secret that he never told anyone in our group

-before he used to take concern about why I was sad .. Like 2-3 times he approached me. These days he get pissed off if Im sad and doesn t bother

- there were few instances before when he acted protective but since few months he doesnt do anything like that

- I noticed 2-3 times he got possessive about me

- earlier I used to tease and flirt with him a lot and even touch him alot, he used to to enjoy that but sometimes he would avoid so I stopped doing that too.

-our friend circle tease us with each other and he doesnt bother about it.

-earlier I always used to sit next to him but since few months I noticed whenever I sit next to him he will walk off to other seat.

So I stopped sitting next to him.

- earlier he even asked me about my crush or what kind of guy I was intrested in.

-sometimes I even noticed he used to stare at me.

So wondering to all these instances I thought he was intrested in me. I really need to know, is he playing mind games or did he lost intrest in me right now or I m just overthinking about it and he never was intrested in me!
