Posting on a throwaway so I don't get called an SJW lol. This happened a couple years ago, wondering about it now. So, I was in a long-distance open relationship with who we'll call Taylor (they're non-binary so going with a gender neutral name). It didn't work out and honestly I don't really remember why, we just stopped talking. Some months later, we started talking again. They had a girlfriend, who we'll call Sarah, at this point who, honestly, I really really didn't like. There wasn't any particular reason for me to dislike her, I just got bad vibes from her. I asked Taylor privately if their relationship was open (because our relationship was open and we're both generally polyamarous people) and they said not for romance but yes for sex. So we sexted and did erotic roleplay for months. And, well, I started falling for them again. So I told them that I loved them. Their response was confusing, they said they loved me too but not in a romantic way. They said that if they weren't dating Sarah, they'd date me. And they said that we could still have a relationship together, just not a romance. That seemed off-putting to me. So I decided to tell Sarah about it. Turns out, she didn't even know about the sex part of it. And she wasn't okay with it. She freaked the fuck out and told Taylor that if they wanted to still be with her, they had to block me, so they did. AITA here?
