Thanks for everything,
In general, romantic relationships can be strained when the planet of love trips the light fantastic a la Ginger Rogers*, just as communications are strained when Mercury the messenger goes through his backward motion. However, because Venus is transiting through Virgo, a healthy fight in couple's therapy could clear up years of bad air. This will be a great time to get to the bottom of things and figure out what has and what is going wrong and therefore you can prevent future problems. Look out though because as the planet moves back through Leo (Aug 13 - Sep 8), the egos take hold and we must take care not to let pride defeat love.
The saving grace of this retrograde is that when Venus transits through Leo, she will also be conjunct Saturn. This dance with big daddy is very favorable for forming long and stable unions. (Although marriage is not recommended during the retrograde.) The key is to be responsible in relationships and show up for the more serious issues in life.
Here's a magickal life jacket to keep you afloat. Carve your names on a brown candle and anoint with lemon oil and pink glitter. Surround the candle in a circle of dried cranberries and light on Fridays during the retrograde period. Lemon and the color pink are sacred to Venus. Lemon is an oil of love and also used to cleanse and detoxify negative energy. It carries a strong healing vibration. Pink represents love and also stress reduction. Cranberries and brown candles are Saturnine and used to ground a relationship and keep it safe and secure. Bathe in fresh lemon juice and eat dried cranberries to infuse this energy into your auras. These ingredients create a magickal seat belt to protect you as you travel down the detours on that highway of love.
May Goddess bless all your endeavors of the heart with light!
