My partner I’ve been together in a situationship with for 5 years recently started his polyamorous relationship with a coworker. (I’m new to this relationship style & been semi struggling with it due to untapped emotions I’ve never experienced in this relationships & in general.) I noticed that he’s more frequently sexting her & when he goes out with her or spends the night at her place they spend more time intimately in bed & where as for me & him it lasts a few minutes or more with him being very satisfied & for me not completely satisfied. I always feel awkward to bring it up because I don’t want him to feel shame but once in a while I’d like to have a little foreplay or make out sesh.

Where I feel worried about him falling out of interest is when I noticed that when his coworker came into the relationship he stopped asking for pics, responding to my sexts, our sex has gotten stagnant, I’ll send hints that I’d like to have fun & have sex around him but nothing…I’ve brought it up to his attention before but his response always is, “she’s a friend I’m having fun with but I’m not seeking a relationship with like I have with you” then will tell me he loves & cares about me very much & is always worried or thinking about me when he’s with her. But I don’t know is that safe for me to trust in those words when I see otherwise?

How do I talk to my partner when he’s not one to talk about relationships or ways to figure out what’s going on between us.
