Confused

I'm in a new relationship. Everything is amazing. But I'm this emotional caring type of person. I've hurt in the past because I love too blindly. Especially my last relationship. Now I've realized that I'm doing the same thing now and I'm trying to back off a little, give him space and not be clingy or too caring (mainly because they always take advantage of this) but now I'm teary because I can't be myself because I'm scared to be hurt . I'm just so confused

I'm not sure if anyone understands this 😔
