Why is it so hard to make/have girlfriends? (I'm female)?

I feel like girls always look me up and down and they don't seem to want to be friends with me. It kind of sounds pathetic because I'm 34 right? I feel like they are intimidated by me and don't ever want to start a friendship. I have some acquaintances but they never include me in anything. I have reached out so much but I never seem to get that in return. I'm smart and attractive, could this be why? I'm not bragging but I think women hate confident women and I'm not overly confident either. I'm actually a very humble person. I don't know why? My husband says they all seem so intimidated by me. My personality is Alpha but I shouldn't have to feel bad about being comfortable in my own skin. I love to laugh, crack jokes and just do regular girl stuff as well as being athletic and outdoorsy. I'm not competitive or jealous. I think all women have their own beauty,talents and strong points. Help? I would love to have more girl time:(
