I feel like this guy is only intrested in me when I dye my hair a certain color and when I dye it back he like stops talking to me/paying as much attention to me we are not dating we just talk and he flirts with me should I keep the dyed color that Him and I both like or keep the "natural" look
That's entirely up to you. Obviously, he like the way you look one way much more than the other. If you are okay with that color, hey, why not. But if you are just trying to keep him, then don't do it. Yes, we all do things to attract others, but we should only do those things that make us feel good about ourselves.
