Happy to be told I am insecure / unreasonable.
One of my close friends is very keen to build an independent (of me) friendship with my DP of 4 years.
She is single and does thrive off male attention and has had a few affairs with married men she works with which perhaps clouds my judgment.
There's been a few times when she's messaged my partner, nothing flirty, just general chat asking how his day was etc or openly suggested they meet for drinks or dinner after work (they work in the same area and she asked in front of me, nothing sneaky) or if she trying a new exercise class and asks if he wants to join her or can help her build furniture in her house etc. He hasn't gone to things he's been invited to and replies to texts in a friendly way but shutting down conversation.
Basically, I find it weird and I don't like it. Mainly because I am always friendly and chatty to friend's partners but would never message them or suggest meeting. I don't think she fancies him and despite her history with married men, I trust her as a friend not to hurt me. But I think she might just like having a stand in boyfriend / male attention from a 'safe' man.
Am I being controlling and insecure to not like this? And I do just not say anything and quietly find it weird?
