We are getting married in May 2019, how soon after the wedding should we go on our honeymoon?

I've known this group for 11 years. Both me and my fiance have tried talking to this girl multiple times throughout. If it's not interesting topics, like celeb stuff, she walks away. Her & her future husband are normally use to being the leader of the group. Since we've moved 5 yrs ago, the group hasn't talked as they normally would have...except ever since the couple took this seminar. They've only been talking to all us again because of the program, despite my prior attempts to reach out. She recently told my fiance how lazy he was and how he needs this $3K+ program because , and her words, "[your] clearly not enough motivation for him." I know I can't get mad because this is coming from a girl who has cheated on her spouse and obviously needs this program. They canceled their wedding a month b4 but still went on their honeymoon & their bachelorette/bachelor parties (wasn't invited or told). For her engagement party, I flew in without a "Hi", "Thanks" or "How've you been?" the whole night. We celebrated the Holidays after our engagement & wanted to celebrate with friends by giving them hand-made gifts while they locked themselves in 2 rooms among 33 people just to do blow. She made out with 2 guys, only admitting it when she was going to get upset that he had a stripper's number in his phone; That doesn't include the 3rd guy when he was studying abroad. She told me my job as a woman was to convince the man to do what is necessary & I'd be the reason for his regret.
