What is your mercury though as you are very straightforward and direct in speaking?.
My mercury is in taurus in 11th house in trine with mars. My gemini venus is in 12th house as well - and I can assure you that a 12th house venus doesn't has the general meaning of secretive relationships - or to attract only man with issues not being free and not to have.
I was always in longlasting relationships - friends as well husbands - and am married for more than 40 years now - 20 years with my first husband and with my second husband 23 years now. So don't worry
