Aligning step parents in genogram

Hi Again, I'm trying to ensure multiple spouses are aligned properly. I have the following in my constructor:

function GenogramLayout() {
    go.LayeredDigraphLayout.call(this);
    this.initializeOption = go.LayeredDigraphLayout.InitDepthFirstIn;
}

I've got the following commitNodes function:

GenogramLayout.prototype.commitNodes = function() {
    go.LayeredDigraphLayout.prototype.commitNodes.call(this);
    // position regular nodes
    this.network.vertexes.each(function(v) {
        if (v.node !== null && !v.node.isLinkLabel) {
            v.node.position = new go.Point(v.x, v.y);
        }
    });
    // position the spouses of each marriage vertex
    var layout = this;
    this.network.vertexes.each(function(v) {
        if (v.node === null) return;
        if (!v.node.isLinkLabel) return;
        var labnode = v.node;
        var lablink = labnode.labeledLink;
        // In case the spouses are not actually moved, we need to have the marriage link
        // position the label node, because LayoutVertex.commit() was called above on these vertexes.
        // Alternatively we could override LayoutVetex.commit to be a no-op for label node vertexes.
        lablink.invalidateRoute();
        var spouseA = lablink.fromNode;
        var spouseB = lablink.toNode;
        var swapped = false;
        //if I have a step father
        if(spouseA.data.relationship_type === 'STEP_PARENT' && spouseB.data.relationship_type === 'MOTHER'){
            var temp = spouseA;
            spouseA = spouseB;
            spouseB = temp;
            swapped = true;
        }
        //if I have a step mother
        if(spouseA.data.relationship_type === 'FATHER' && spouseB.data.relationship_type === 'STEP_PARENT'){
            var temp = spouseA;
            spouseA = spouseB;
            spouseB = temp;
            swapped = true;
        }
        // prefer fathers on the left, mothers on the right, as long as we haven't already swapped and we're not a step parent
        if (spouseA.data.s === "F" && !swapped && spouseA.data.relationship_type !== 'STEP_PARENT') { // sex is female
            var temp = spouseA;
            spouseA = spouseB;
            spouseB = temp;
        }
        // see if the parents are on the desired sides, to avoid a link crossing
        var aParentsNode = layout.findParentsMarriageLabelNode(spouseA);
        var bParentsNode = layout.findParentsMarriageLabelNode(spouseB);
        if (aParentsNode !== null && bParentsNode !== null && aParentsNode.position.x > bParentsNode.position.x) {
            // swap the spouses
            var temp = spouseA;
            spouseA = spouseB;
            spouseB = temp;
        }
        spouseA.position = new go.Point(v.x, v.y);
        spouseB.position = new go.Point(v.x + spouseA.actualBounds.width + 30, v.y);
        if (spouseA.opacity === 0) {
            var pos = new go.Point(v.centerX - spouseA.actualBounds.width / 2, v.y);
            spouseA.position = pos;
            spouseB.position = pos;
        } else if (spouseB.opacity === 0) {
            var pos = new go.Point(v.centerX - spouseB.actualBounds.width / 2, v.y);
            spouseA.position = pos;
            spouseB.position = pos;
        }
    });
};

It's getting close but for some reason it's not maintaining the father position to the right of other siblings:

Any idea on how to push the father back to the center (right of other siblings)?

Thanks,
