Recently things have felt different between my partner and I. Communication wise we use to talk all the time like every day full conversations and now it’s maybe every couple days with their replies being very short. This started maybe two months ago when they were experiencing burn out which was understandable at the time because they were going through a bunch of life changes rapidly. Trying to make plans with them seems difficult as well even just trying to get a phone call (long distance). Our dynamic is mono - poly me being mono, and I know they see their other partner because they mention it to me when they do. Lately as well I see them online on the dating app we met on throughout the day mean while not replying to my text from the day before. To clarify that I still use said app to keep in touch with some friends. I’ve asked my partner if this is something they still want or if anything has changed and they say they do and to not worry. Yet something just isn’t sitting right with me. Help?
