My guy “friend” is very confusing?

Last week i sent him a picture of myself and he said “nice pic”
Then yesterday he brought up the pic and said “just so you know you looked very beautiful in that pic” which i thought was nice but very unusual of him
Now he’s mean to me? Like he seems off or meaner than usual ig
Anyway what does that mean why is he acting weird 😭😭😭
