He/Venus is moving slowly toward stationing retrograde and then moving away from you/Mars. So Venus and Mars ultimately separate before they meet by conjunction.
Your two significators are in your 5th house of romance, but his turned 11th. So I see him being more motivated by ideas of friendship, if what he is doing is actually anything more than curiosity [Moon applies to sextile Mercury]?
