Moulin,
In the chart you are ruled by mercury.as your question involves travel, thats appropriate. The ruler of you is in your h5 of childrens matters-it applies to a trine with mars, although mars is not in a good state, dignified slightly by being right on the mc., which is also ruled by mercury.As this is the only aspect your ruler applies to, we look to the moon- in your 12th house of secret sorrows, with an exact opposition to uranus in your h6-so yes you are frustrated and feeling the urge to make a big change, but the moon applies to a square to mars.....so we look to your ex- h7-ruled by jupiter and we see that mercury and jupiter make no aspect other than a semi-square, which, even though it *doesn't count* shines some light on negativity between you.
The ruler of your children is saturn-saturn does apply a trine to his ruler, but his ruler is in his h10- his work- thats where his interests are.
As the house that rules the trip itself is H9, we see a fixed sign on the cusp- Taurus...ruled by Venus.As the ruler of the trip is venus we see venus will conjunct Jupiter,the ruler of your ex....in 7 *somethings*...The ruler of the trip will trine the ruler of the children, but both planets are in the sign of saturn and your exes ruler is debilitated in fall in cap. Your ruler is not too happy in freedom loving aquarius, either....the ruler of the kids also debilitated...
So how will jupiter respond to mercury? Well they are both *thinking of the children*(being in saturns sign....) I think you will ask him and he will not co-operate with you *for the children's sake*
As your ruler will go retrograde in a day or two I'd say you will change your mind and not go.
Hope that sheds some light.
best wishes, Lillyjgc
