William Law committed adultery. Then he was excommunicated…Though he apparently didn’t agree with polygamy… he did want to be sealed to his wife which Joseph wouldn’t do on account that he committed adultery. We have an eye witness account that it was Mrs Law that beckoned Joseph to come talk to her, not Joseph seeking to talk to Mrs. Law…After that, it was her word against Joseph’s word and William had already had enough of Joseph. He took matters into his own hands. William Law’s journals say Joseph made advances at his wife, but the evidence suggests otherwise.
Where are you getting your history? I need to see your source that says Law committed adultery, because that’s not what the historians are saying. From LDS historian Grant Palmer in his paper
Why William and Jane Law Left the LDS Church in 1844:
*It is well documented that Joseph Smith took at least thirty-three plural wives between 1841 and 1843.16 By June 23, 1843, Joseph Smith had already married twenty-one women, including a number of married women and several young teen wives. Because of these activities Emma Smith was not happy in her marriage with Joseph. William Clayton, Smith’s personal secretary, recorded a conversation in his journal on this date that Joseph Smith had with his wife: "He [Joseph Smith] knew she [Emma] was disposed to be revenged on him [Smith] for some things. She [Emma] thought that if he [Joseph] would indulge himself she [Emma] would too."17 Joseph Jackson supported William Clayton’s private entry. Jackson said that Joseph told him: “Emma wanted [William] Law for a spiritual husband, and she urged as a reason that as he had so many spiritual wives, she thought it but fair that she should at least have one man … and that she wanted Law, because he was such a ‘sweet little man.’”
Between June 23 and July 11, 1843, Joseph Smith receives a commandment that is mentioned in a July 12, 1843 revelation: “A commandment I give unto my handmaiden, Emma Smith … which I commanded you [Joseph] to offer unto her” (D&C 132: 51). William Law, Smith’s counselor in the first presidency, described the content of this “offer”-revelation that Smith used to appease Emma. Law wrote: "Joseph offered to furnish his wife, Emma, with a substitute for him, by way of compensation for his neglect of her, on condition that she would forever stop her opposition to polygamy and permit him to enjoy his young wives in peace and keep some of them in her [mansion] house and to be well treated, etc."19
While Joseph and Emma Smith agreed to this sexual offer, William and Jane Law did not. Jackson, continuing with his narrative said that "He [Joseph] and Emma had both tried to persuade her [Jane Law] of the correctness of the doctrine, but that she would not believe it to be of God."20 With the Laws having rejected the offer, Joseph Smith received D&C 132, on July 12, 1843. Verses 51-52, 54, now instruct Emma:
That she stay herself and partake not of that which I commanded you to offer unto her; for I did it, saith the Lord, to prove you all, as I did Abraham … Let my handmaid, Emma Smith, receive all those that have been given unto my servant Joseph … I command mine handmaid, Emma Smith, to abide and cleave unto my servant Joseph, and to none else. But if she will not abide this commandment, she shall be destroyed, saith the Lord; for I am the Lord thy God, and will destroy her.
William Law recorded Joseph and Emma’s comments on these verses: “He [Joseph] thought the revelation would cause her [Emma] to submit peacefully, as it threatened her removal if she did not.” Emma confided to Law that the revelation, which she did not believe in, was a “threat against her life,” if she did not comply.21 Law said that Emma, "Spoke repeatedly about that pretended revelation … [and] says,] ‘I must submit or be destroyed. Well, I guess I have to submit.’"22 Emma submitted to Joseph’s instruction, but Joseph continued his proposals to single and married women until December of 1843, including Jane Law.
Several months after this sexual “substitute” for Joseph incident, probably during November-December, Joseph Smith made a play for the “attractive” thirty-year-old Jane Law.23 William wrote in his diary on May 13, 1844, that, "He [Smith] had lately endeavored to seduce my wife, and had found her a virtuous woman."24 Alexander Neibaur, a close friend of Joseph Smith, recorded: "When Mr.] Law came home [one evening,] he Inquired who had been in his Absence. she said no one but Br Joseph. he then demanded what had pass[ed.] Mrs.] L[aw] then told [him] that Joseph wanted her to be Married to him."25
Joseph Jackson said much the same when he wrote, that it was "Shortly after the … (15th of Jan, 1844) that Joe[ph] informed me in conversation, that he had been endeavoring for some two months, to get Mrs. William Law for a spiritual [polygamist] wife. He said that he had used every argument in his power to convince her of the correctness of his doctrine, but could not succeed."26 Smith shared this information, according to Jackson, because Smith wanted Law “removed.” Jackson said that shortly after January 15th:
One Sunday morning, Joe[ph] and I had a long talk concerning Law, in which he avowed, not for the first time, however, his determination to put Law out of the way, for he had become dangerous to the church of Jesus Christ of Latter Day Saints, and that it was the will of God that he should be removed. He, however, wished to proceed in such a manner that he would be able to get Law’s wife.27
By January 1, 1844, it is clear from William’s diary that the Laws have rejected Smith’s proposal.28 On January 8th, Law is dropped as a counselor in the first presidency and on April 18th, the Laws were excommunicated from the church.
