Can you make some examples of how feminists have tried to improve the lives of men?

Because of feminism, more women have been able to get educated. Because of education, they have been able to contribute to running all societal institutions: political, judicial, educational, spiritual, financial and so on. Thus, they have improved the lives of men, by taking some of the pressure off them. They don't have to feel responsible for everything all the time. Women can help.

Because of feminism, women have been able to get more jobs. Occasionally these jobs are well-paying. Even at 77% of what men make (Source: https://www.whitehouse.gov/equal-pay/career), these jobs allow women to contribute to feeding their families. Men don't have to feel totally responsible for supporting their families. Women can help.

Without feminism, women would be stuck in the 19th century.

Are you familiar with The Declaration of Rights and Sentiments produced for the Woman's Rights Convention, Held at Seneca Falls, N.Y., July 19th and 20th, 1848. Here's a bit of it. I think you'll find it interesting.

The history of mankind is a history of repeated injuries and usurpations on the part of man toward woman, having in direct object the establishment of an absolute tyranny over her. To prove this, let facts be submitted to a candid world.

He has never permitted her to exercise her inalienable right to the elective franchise.

He has compelled her to submit to laws, in the formation of which she had no voice.

He has withheld from her rights which are given to the most ignorant and degraded men—both natives and foreigners.

Having deprived her of this first right of a citizen, the elective franchise, thereby leaving her without representation in the halls of legislation, he has oppressed her on all sides.

He has made her, if married, in the eye of the law, civilly dead.

He has taken from her all right in property, even to the wages she earns.

He has made her, morally, an irresponsible being, as she can commit many crimes with impunity, provided they be done in the presence of her husband. In the covenant of marriage, she is compelled to promise obedience to her husband, he becoming, to all intents and purposes, her master—the law giving him power to deprive her of her liberty, and to administer chastisement.

He has so framed the laws of divorce, as to what shall be the proper causes of divorce; in case of separation, to whom the guardianship of the children shall be given; as to be wholly regardless of the happiness of women—the law, in all cases, going upon the false supposition of the supremacy of man, and giving all power into his hands.

After depriving her of all rights as a married woman, if single and the owner of property, he has taxed her to support a government which recognizes her only when her property can be made profitable to it.

He has monopolized nearly all the profitable employments, and from those she is permitted to follow, she receives but a scanty remuneration.

He closes against her all the avenues to wealth and distinction, which he considers most honorable to himself. As a teacher of theology, medicine, or law, she is not known.

He has denied her the facilities for obtaining a thorough education—all colleges being closed against her.

He allows her in Church as well as State, but a subordinate position, claiming Apostolic authority for her exclusion from the ministry, and, with some exceptions, from any public participation in the affairs of the Church.

He has created a false public sentiment, by giving to the world a different code of morals for men and women, by which moral delinquencies which exclude women from society, are not only tolerated but deemed of little account in man.

He has usurped the prerogative of Jehovah himself, claiming it as his right to assign for her a sphere of action, when that belongs to her conscience and her God.

He has endeavored, in every way that he could to destroy her confidence in her own powers, to lessen her self-respect, and to make her willing to lead a dependent and abject life.

Now, in view of this entire disfranchisement of one-half the people of this country, their social and religious degradation,—in view of the unjust laws above mentioned, and because women do feel themselves aggrieved, oppressed, and fraudulently deprived of their most sacred rights, we insist that they have immediate admission to all the rights and privileges which belong to them as citizens of these United States.

Meanwhile, it's obvious that you feel aggrieved and you probably have good reason.
