Recently a guy who had been vying for my LTR around a year back (creeping. She'd blocked him everywhere) managed to talk to her on Facebook and found some closure. I've been with this girl for more than 2 years and have no major complaints. She's obedient, submissive and isn't high maintenance.

Recently she's been talking a lot with him, which is fine. It doesn't really bother me that she talks to him. The problem is she's relaying all the information to me. She goes on and on about how he's changed, how he's so mature and all that wonderful deep conversations they're having.

Them talking is not an issue. I'm not insecure, and even if she does leave me for him I wouldn't really care. It took a while to become outcome independent but I have. My question is how do I make her stop talking about him without appearing like its getting to me? It really isn't, but hearing her go on and on about him is frankly irritating and gets old fast. Do I just tell her to stop talking about him? Would that make me seem like I'm insecure?
