I am not supporting your decision, because you are the first person responsible for such an issue. Why don't you control her from the starting itself? When yr income became less you are controlling. First of all talk to her and find out where is the overexpenses are coming and control. If your both hands are clapping then only the sound is coming!!! Wife means half of your body and soul. When u start to look another one, u will get worse than this!! If it happened then what you will do. Nothing can be imposible when both of you consult each other and reach an amicable solution. First u think is this right and act accordingly. WISH U ALL THE BEST
