My wife and I recently decided to open our marriage. One of our rules is that we cannot have sex with people we had sex with prior to our marriage/relationship. However, my wife currently engages in occasional text and phone conversations with someone from her sexual past (by occasional I mean a few times a month). Additionally, she's seen him in person multiple times in the past year (dinner and drinks once, at a party another time). She says it's platonic and I'm inclined to believe her. But when I tell her that I'm uncomfortable with their relationship, she compares it to my communication with someone from my sexual past who I've had a handful of brief text exchanges with in the past year, and who I haven't seen or spoken to on the phone in almost 10 years....is this a fair comparison?
