Hi guys -- long time browser, first time registering/posting. I have seen a few threads that touch on what I want to talk about, but they don't exactly hit the nail on the head. I am currently writing my second novel in a 5-part series, and just planning to myself exactly how things are going to unfold (I know the main plot points, and had a general idea of what couple situations would be like), and I am starting to worry that my characters are naturally going in a direction I do not want them to go. First case: My male protagonist and his best friend seem to be the only couple that makes sense. Each have a respective female love interest, but I always knew that neither of them would end up "getting the girl". In a weird twist, these two seem to be the only emotionally functioning duo -- but having said that, I know that the "alpha" one would never initiate anything, nor would he consciously act on any bisexual tendencies; and my protagonist would be waiting for his friend to initiate anything before feeling comfortable. It's a weird issue of.... logically they would be too unwilling to act on anything, but they are so drawn together and have a great connection. Second case: The male protagonist's girlfriend has some serious angry/sexual tension with another heterosexual girl. This other girl (who is the protagonist of a side series) has a WHOLE other storyline going on: she gets engaged to her long-term high school boyfriend, only to end up breaking off the engagement in the last book and finally going off to establish herself as an independent person who isn't defined by the people in her life. For the MP's girlfriend, she is a conservative Christian. For the other girl, I know that at this point in her life, the only person she has eyes for is her boyfriend, she is extremely loyal and would never cheat on him, or have sex with someone she does not have a deep level of emotional intimacy. Overall, I just feel like these 3 characters (not so much the other girl, she seems to be pretty focused on her boyfriend) are naturally drawn to the wrong people I had in mind for them. Should I just let these relationships unfold, regardless of the end point I had in mind, of can I get away with having is as an ambiguous subtext?
