I have name changed as this is very outing. I have been married for ten years, we have 1 child together. Around 5 years ago we decided to open up our marriage. Neither one of us felt we were getting our sexual needs met. I am bisexual and have had a girlfriend for around 18 months. My husband has seen a few women off and on. We have really open and honest communication with helps.
He is in the military and is working half way across the world just now until next month. He let me know he was online dating and had met a woman he was interested in - all good. However, this woman reached out to me via social media to confirm he was in an open marriage. I was not comfortable with this, I don't really want to know who he is having sex with and I feel this woman contacting me shows a lack of boundaries on her part. I replied to her to confirm he was but spoke with my husband and asked that he not see this woman again as I don't feel comfortable, she seems like drama to be honest. He agreed he wouldn't see her again.
Husband and I have our location on and have noticed past few nights (his time) it's suddenly been unreachable, as if he's turning his phone off. I asked him and surprise, surprise, he has been continuing to see this woman. He says purely sex, they aren't dating or anything. This just makes me feel highly uncomfortable though, as this is the first time (that I know of) that he has lied to me and I just feel almost like I have been cheated on.
Not sure what to do, he thinks I am being unreasonable as he doesn't think it's a big deal to reach out. But we had discussed this and would prefer no communication with each other partner and it's not been nice to see who he is fucking.
AIBU to think this is a betrayal? How can I believe anything he says now?
