I feel no emotions toward anyone?

I've been in several relationships. Longest would be a year and a half. I realized I feel no emotions toward anyone. Someone could cry and I feel nothing. My counselor said she thinks I have bpd but that is another story. I can kiss someone and I feel nothing. It's just meaningless.... Idk why..... I can laugh and feel sometimes but I feel no emotions toward anyone at all. No matter how attractive they are! Why?
