Hey! Me and my partner of 5 years just opened our relationship this month after a while of discussing it. I wasn't super enthusiastic for a long time, but reading a lot on the subject flipped a switch in my head.

Today, she told me that she had sex with a friend for the first time and I don't quite know where I stand on this. At first, I felt nothing special and just carried the conversation along, asked some questions and then went with my day. The weird thing about it is that I don't recognize any strong jealousy or insecurity as I did before when we talked about it... It's just a bit hollow inside.

I'm happy that her relationships are evolving but at the same time I feel like I'm losing interest in ours.

Does anyone relate to this or am I weird?
