Dear Dr. NerdLove: I just recently celebrated a three year anniversary. We've always gotten along really well, we have a good sex life, we have fun, we live together, and my partner is kind and attentive to my six year old daughter that lives with us part time. There's not a lot of intensity and depth but we're kind to each other and there for one another. There shouldn't be anything wrong, but yet... I find my mind straying. I have a really good friend. We've been friends for years, nothin...
