I recently found out that my fiancé used to consider herself polyamorous but says she isn’t anymore. We met and she was still married but separated. She didn’t tell me this until a few months after we started dating. She had been separated for maybe 4 months prior to us meeting but not officially divorced. She said her husband had been cheating on her and was telling others they were in an open relationship. She said a week after she found out (a month before her bday) she had a trip planned to California but when she found out about her husband’s affair she told him she was going on the trip alone. She went to California solo and her Best friend (female) flew to California too. A male friend that is a swinger and also a poly surprised her and when he arrived upgraded her hotel room to a suite so they could share it. When she told me the story it was just that. Nothing more. Just a couple friends that came and the guy friend came after she told him about her husband’s affair to show her support. The best friend (female) left a day before she and the male friend did. I later found out that On their last night they had created a profile on a swingers club’s website to attend a lifestyles event. The profile was linked to her email address and her cell number and the pics showed her and the male friend. The description said that they had been in the lifestyle/poly word for over 10 years and both labels themselves swingers looking to meet like minded people and possibly more fun. When I discovered all of this I asked her and she denied ever creating the profile and that they never attended a swingers club in California and had you idea about the profile created. I found the emails in her email account but she still claims she never created the profile not attended the club. Whenever I bring it up she flips out and goes crazy to the point when I just drop the topic. She says she never slept with the male friend and never slept with anyone except me since her separation. I also discovered a adult friend finder profile with the same username that also was linked to her same email and cell number and it also was a paid subscription that was coming out of her bank account monthly up until a month after the at trip. That account was active for 3 years and paid for the entire time. She claims she never created it and says her ex husband must have done it and she never realized the monthly payments. She is the type of person that closely monitors her bank transactions so I’m reluctant to believe she had no idea. The description on that profile is speaking as if it were here saying things like “discreet couple that has a lot of friends in the lifestyles world and looking to meet like minded people or groups. I (wife) looking for a bisexual male/female for some fun.” I asked her to ask the male friend over the phone if they went to a swingers club. He didn’t know I was present when she asked and he said yeah we went to a swingers club. She immediately said to him “we didn’t go to a swingers club.” And he just remained silent because I think he just realized he slipped up. To this day when I ask about it she denies the entire thing. I asked her to search her email for the club name and she refused to do it and again flipped out. Later that night she searched it when I wasn’t around and deleted the emails found. The next day she left her email account open on her computer and I searched and found them in the deleted folder. I screenshotted the emails and left them open on her Pc so that she knew that I knew she wasn’t being honest. She again flipped out and now accuses me of planting the emails there even though the timestamps predate our relationship and even before I met her. She usually is not one to lie but I strongly believe in this case she is. I tell her I don’t like the friendship with that male friend and says she’s not going to stop being his friend. What do you all think? Please ask questions as I have more details that are too long and complex to explain here but i definitely want advice and hear thoughts on this so I know weather or not I’m making the right decision to marry her. I was previously married for over 14 years and was cheated on by my ex as well. I love my fisnce but don’t want to be a fool and be cheated on again. Thanks in advance for hearing my story and providing any advice.
