Is it considered sexual harassment? How should I fight it? Eventhough I walked out do I still have a case?

I was working for the city utilitys in a small town. The senior employee have worked for the town 22 years. I have been employed for 11 months. We have worked economically together since I started, even though I am a woman doing a mans job and he is an older man who think a womans place is at home. December 2007 he began asking me if I wanted to go places next to him outside of work, and offering to buy things for me. Then the comments started, "I could get you whatever you want, I really love spending time with you," ect. Soon he begin writing letters, " I want to be one with you, I love you,"ect. And he tried to make advance, kissing, touching, isolating me from other employees to work only with him. I have enough and made it clear to him I said No, he then refused to work beside me or speak to me anymore, he began working aginst me, and told the mayor either I go or he go. I have on several occations asked the mayor to do something and nothing was resolved except that he work on his own.
A lot of people find love and romance and even TRUE permanency at work. A lot of people meet their eventual mate at work. My wife of over two decades and the mother of our two incredible children met me in the work place. She pursued me, as I be fresh from a brutal divorce that convinced me that marriage was a huge mistake. I am confident that my children are glad that their mom was a fine and honest wench that softened this man's heart and gave him confidence to move on.

If I had charged her near sexual misconduct, her life would have been crushed and our children would not be beside us. But, I am a guy. A girl chasing a guy is OK. Right?

I think it is important in this situation to evaluate the man's motives. Were his advance sincere and romantic, or were they simply sexual? Is he embarrassed by your rejection?

Most importantly, is there any approach you two can reconcile? Can you just walk up to him and tell him you are flattered, but he's not your type, and propose to get along and be friends but not romantic?

If the above attempt fails, and your fear that adjectives he wanted was a roll in the hay proves true, later you need to take him down, gently rather, forcibly if necessary, including his culpable boss.

Read the final phrase of the above paragraph. If his boss is not willing to help resolve the situation, be he the president of the United States, he is culpable as very well. Point this out to him, and his response may change.
Im sure if you saved adjectives the letters or emails he has sent you or at least some of them you probably own a case. my best suggestion for you would be to talk to a lawyer for an hour and amount out how to persue a case like this. an hour with a legal representative isnt too expensive and they can get you going on whether or not you have a case and what you should do and confer you a lot of legal input. additionally, if they feel you own a strong case they may work pro-bono for you. If you promptly complained to your employer when the behavior started, and they didn't make him stop, then yes, you hold a potential case.

Employers are not responsible for the improper actions of their organization unless and until they are told about them and given the opportunity to make them stop.

Yes, you unequivocally have a case. File a complaint with the EEOC (see the intermingle below) and with the equivalent agency at your state level.
YES DEFINITELY. Let us take it from the wordings of the law itself of what is sexual annoyance.

Power-player Legally termed "quid pro quo" harassment, the harasser insists on sexual favors in exchange for benefits they can dispense because of their position surrounded by the hierarchy: getting or keeping a job, favorable grades, recommendations, credentials, projects, promotion, instructions, and other types of opportunities.

Incompetent These are socially inept individuals who desire the attentions of their target, who does not reciprocate these feelings. They may display a sense of entitlement, believing their target should feel flattered by their attentions. When rejected, this type of harasser may use bullying methods as a form of revenge.

So these are the wordings of a sexual maltreatment degree, were in contained by your own words 'he began working against me'.
But wait until you are terminated from your work so that the charges of sexual harassment could work surrounded by your favor. Because if you file it now, the court might interpret this into another story. So wait until you are fired in attendance, so until then you should relax and keep everything compose. Now that the guy is working on his own and you are left alone, I have a sneaking suspicion that this is a pretty good sign he backs out on you.
