I'm feeling distanced with two of my F/Os

I'm a poly shipper and I loved my f/os equally but since Mikoto came I feel I don't love Hubert and jaehee that much, I would feel bad if I "divorce"/cut the relationships with them because I'm married to Hubert and had a deep connection with Jaehee.

I don't feel that connected to them, specially with Jaehee, I almost exclusively feel it with Mikoto and rarely Hubert, jaehee none anymore!

I don't know what to do.
