I can't imagine my husband meeting with another woman and not wanting me to go along. If she is worth meeting/talking with and he feels the same about you, why isn't he introducing you to her too? If I didn't like something, my husband would probably drop it like a hot potato since he wants me to be happy, not make me feel bad/odd/embarrassed to be feeling what I feel. It's not like you're stopping him from meeting her in the first place; he did that but what is so interesting that they're keeping it up? It's not like he works with her or had a prior, recent, relationship with her.
