F was the first. She was 30 years younger than him & a co-worker. I knew from the beginning that the relationship would not be successful. Someone so young could not possibly be emotionally mature enough to handle a 30 year difference in ages, as well as a polyamorous one. Although they stayed together romantically for only 2 months, they still work together. Several months ago, he wrote her a letter saying that he respectfully requested that she not act anything but professional with him, such as not sending "drunk texts". She read the letter, never replied, & did as he requested. He stills longs for her. The thought makes me sad that he is sad.
K was the second. We both have sex with K from time to time. She is not a romantic partner. She is more of a play toy for us, although her place in our personal lives seems to be on the decline. She holds traits that we do not find attractive, such as her weight, smoking & the lack of time we are able to share with her, because of her young daughter.
I am nervous about him dating M. The biggest issue I have is she also works with him, just as F did. In fact, all three still work there to this day. I would really hate for his relationship with M to end like the one with F. I cannot imagine working among the same small staff, with two former lovers staring at you day in & day out.
Although I have voiced my concern, I am not sure if it has caused him to pause & think. I am not interested in him completely stopping the path of the relationship, I just want him to think. I will speak to him again, before their first date on Thursday.
