Am i paranoid or normal?

I met a man and we got on great. I like an idiot asked what type of woman he liked and he said dark haired. I am redhead. I still get upset over that especially if he looks at a dark haired woman. My ex liked dark haired women and made fun of me and even went after my dark haired sister and i divorced him and he is with a dark haired filipino now but unhappy and wants me back..haha..no way jose. anyway.....should i accept he loves me as he professes and is he just looking because the woman is beautiful...simple as that or should i leave him and let him find the woman he finds to be his ''type''. ARe men happy with women who aren't their ''type''? ARe you always going to be longing for that type? He gets mad at me if i bring it up and says i am above any type but he still stares at dark haired women alot. there are days my stomach hurts because of it. I always feel like i should dye my hair black. I am a mature woman and secure in myself but this is my achilles heal and it hurts. Should i worry. My ex got what he wanted in the long run. thin and dark. He likes to brag about how thin and dark she is but he wants me back..haha. i find that hilarious. I think sometimes i should let my guy free to find his ''type'' and maybe he would be happier. he says stop saying that, that he loves me but i want to be fancied too not only loved. You men seem to seperate and love. A y dark haired women take your fancy but me, a nice, good, fun, pretty redhead is what he loves yet it makes me feel less because i am not his fancy. do you understand? Am i nuts? or am i right in a way? thank you.
