NT/ND Relationship

I'm an NT female in a LDR with an Aspie male who's also on the BPD spectrum. After a long stretch of affection and virtual date nights which really brought us closer, my BF went into an energy dip. I'm normally accepting when that occurs because I understand him in that sense.

However, during this recent lull, he joined Meetup and started to pursue other social outlets instead, including women's book clubs and women's gaming groups.

In an NT relationship, I wouldn't tolerate this, but I understand the ND mind works differently, so I'm seeking advice and clarity from other ND's, while he processes my asking him for clarity, because I'm guessing he's going to need to sit with this for a bit to determine how he feels and responds to my message.

Thanks so much.
