I, 24M have a partner 24F that went to a family member’s destination wedding that I couldn’t go to that weekend. She connected with a lot of her family that she hadn’t seen in a while and family friends. At dinner the night before the wedding, she started to interact with a guy who is a good friend of her cousin. He 35M is a good friend with her cousin but of course was too old at the time to be a friend of hers while she was growing up. After she got back, she has consistently been facetiming him at times I’m not home or will leave the house/ room to talk with him in private. When. I asked what they were talking about, she is vague. I also have comfimed that she does talk about issues in our relationship with him. The reason this set of my alarm bells is that she has had 2 inappropriate sexual text-based relationships with guys in their mid to late thirties. When confronted about seeing her conversation, she says that there are no whatsapp conversations and they only facetime. Yesterday, she told me that she had a conversation about my discomfort with him talking with her, and this started a pretty heated argument. Am I reading too much into this, or does this actually mean the behavior is happening again?
