I really don’t understand jealousy in relationships. Isn’t jealousy a lack of trust? I have been married for 20 years and I completely trust my wife. I had a situation happen recently where a co worker asked me for a favor. She had to give me her number for me to do this favor for her. I sent her a few text messages related to the favor she asked, all professional. Apparently her husband read my text messages and became jealous and my co worker is acting weird with me now. I feel like ok maybe you shouldn’t have asked me to do you a favor and given me your number if you know your husband is the jealous type. I don’t monitor my wife’s text messages or social media profiles. I’m just annoyed because it’s created an awkward situation and as I said, jealousy isn’t a part of my relationship so it’s very difficult to understand. Thoughts? Opinions? Advice?
