Can you predict separation as of next year or not?

All set, thanks

I can't say if there will be a separation or not, but in the spring of next year, in March, the ruler of his 7th house of relationship, Saturn, will undergo a sextile from transiting Saturn. This is while Saturn is traversing his 7th house. That transit to natal Saturn is followed soon thereafter by a square from Jupiter, strong in its dignity, so with lots of energy both by square aspect and by Jupiter's essential dignity. Plenty of energy to shake things up.

All of this is preceded by transiting Saturn, which symbolizes learning hard life lessons, conjuncts natal Chiron, the Wounded Healer, also in the 7th.

I can't say for sure if there will be a separation, but there may be some very significant events in his relationship with his wife, perhaps that may cause him to separate.
