IAMAn Only Female in a Male-Dominated Construction Job and --SURPRISE!-- am Having a Hard Time Fitting In. In Need of Advice, Please. My Gratitude in Advance.

I am, indeed, very sensitive, but i can also "roll with the punches" for the most part and have earned a well-deserved reputation for being a hard worker among most of my colleagues. PROBLEM: some of my "tougher-guy" colleagues act waaaaaaay too cold around me when i try to be friendly and it's pretty much driving me insane because it's just a shitty way to be. I feel as though they treat me like i did something wrong and they won't forgive me, even though i have no idea why anybody would ever treat me this way. I feel very confused and ostracized. I have already wondered if my coworkers might be attracted to me, but their obviously mean behavior really does make me think otherwise. I feel like i've let them down in some way. Any opinions or insights to this problem are greatly appreciated and i thank you for reading this.
