Hi,
Going by the birth details, you seem to be in the midst of (5th & 12th lord) Venus/Shukra Maha-Dasha. He is considered to be the Natural significator or Naisargika Kalathra-Karaka. His presence in the 7th house of Kalathra-Sthana calls for validation of Karaka-Bhava Nashaya. On the sidelines, he has also activated the 7th lord Jupiter/Guru placed in his Uccha-Sthana or sign of exaltation in the 2nd house of Wealth Accumulation and Family Expansion. Jupiter is loosely conjunct Ketu.
Given that Udaya Lagna is placed in Mithuna Rashi, Lagna Lagna Lord Mercury/Budha is never too happy or comfortable being placed in the 7th house of Kalathra-Sthana. Further, placement of Sun/Ravi in the 7th house and posited in the Lunar Constellation of Moola/Mula Nakshatra does not bode well.
On my part, I’m inclined to think there is lack of attachment (including with siblings – if any) and compatibility. So, chances of separation is very much there. But there are also strong redeeming factors that seems to be pushing the envelope.
Take care…
