Huseyin,
According to Vedic astrology my observations from your birth chart is as follows:
1. Aries ascendant and occupied by Mercury and Venus. Mercury is lord of sixth house and third house, with the lord or Spouse house exchanging its position with Ascendant lord Mars (Retrograde). That indicates that you have a passion with your spouse, but due to disturbances (hidden) your married life or spouse or you or both of you are disturbed.
3. Fortune and Bedroom lord Jupiter (Retrograde) is aspecting your spouse house lord. That’s why even after separation you have not gone for divorce, although Mercury will try to do this (I mean some your close persons will try to disturb and advise you to go for divorce)
4. I won’t say that you are not facing disturbed married life, even in other marriages (if you go for), your situation will be almost same.
5. Currently you are passing through Mahadasha of Rahu (NN) and anterdasha of Mars with Pratyanter dasha of Mercury. During this period you may think more for divorce, but after May 2013, Jupiter Mahadasha will start, situations may improve.
You have three Retrograde planets, two are involved in the house of spouse.
If you want then you can find out the solutions after May 2013. Solutions in adverse conditions.
If you want to go for divorce then probably by Third week of January.
I will not suggest for divorce, try to find out solutions.
