Numbness in a relationship

How do you deal with numbness in a relationship?

If “I think I feel numb towards another person”…it gives me a feeling of nothing, which might be indifference. I think intellectually its because I am resisting feeling some kind of other emotion could this be right?

How can I explore what sits below the surface, what are good questions to ask myself?

Is there any guidance on this in the vault ?
Thank you
