Excerpt from my latest Sasstrology article (please leave comments on the Sasstrology site):
"Natal Mercury is often glossed over in the astrology of love and relating. The planet of communication and information gets bypassed in the rush to focus on juicier planets, like Venus or Mars.Mercury may not be sexy, but it has a lot to say about how you approach partnerships. If natal Mercury rules/sits in one of your relationship houses (5th or 7th) or conjuncts Venus or Mars, its influence on your love life will be obvious. I’m not going to address those scenarios here, but I am going to look at examples where natal Mercury is not obviously connected to a relationship planet or house."
