I have never found anything that I can attribute specifically to Retrograde Venus. When I see a Venus retrograde in a chart, I never know how exactly it would be different in the person's life if it were direct. I have read interpretations of retrograde Venus but have not been able to confirm it personally.
For example, astrologers say that if Venus is retrograde in a natal chart it indicates 'not feeling loved, or not receiving the love one needs...there are problems in the area of relationships. The lesson is about finding a sense of self love' etc etc
But Venus in Capricorn has the same indications. So I am not sure that it is that significant that it appears to be moving backwards, or not.
