Choosing your topic for the constellation. “Me and My Partner/Spouse” issue.

I’ve seen many cases of disappointment after constellation work when people choose to work on the topic “me and my partner/spouse”.
So, there are some problems in relationship and people would like to work on them.
Such constellations often are 2 roles work (her and him, no one else is required) with the result “pure love” in between of two of them: two people hugging and not even the thinnest paper can be squeezed in between. Such a love.
Why is that?

Such a love and problems in relationship?
On the soul level there is pure love, wonderful connection.
In the reality there are problems.
Because, for example, except this pure love there might be reasons causing the problems, like:
-Traumas in the Family Past.
There might be traumas in the family past (systemic traumas) on her and/or his side; which means living someone else’s life, not belonging to yourself. This might cause health problems, fear, aggression and so on in many life situations and as a result family problems.
– Not accepting parents. Problems in relationship with the parents.
If, for example, the child was separated from the mother then later, when he/she is an adult, this causes inability to love the partner (spouse) because of the fear to lose him/her. Or if feeling better than the mother or the father – this also causes relationship problems. And so on.
What to do?
Work on yourself. On your own problems. Step by step, if cleaning out your own problems, you’ll be able to open yourself for your successful relationship. Also this is very helpful when both partners work, not just one.
