I'm (29m) an extremely introverted and asocial person.
Early in the relationship with my gf I was expressive and made her feel loved. But in my natural state I'm not so expressive.
2 years into the relationship my gf started feeling I don't love her and care for her. But that's not the case. I got tired of the constant fights and arguments but I still liked her.
Is there anyway an asocial introvert can make a BPD feel good by giving constant assurances?
