Unfortunately, when you realize that the relationship is beginning to crack or is already completely broken, it is often quite difficult to try to fix something spiritually at such moments (you just don't want to).  Of course, many will choose the option: disperse.  Since this is the easiest way to solve this problem. BUT! Unfortunately, you will solve in this way only an external problem, but not an internal one, because not one, but BOTH spouses are to blame for the destruction of the relationship, and there is demand from both. 

Therefore, if the relationship starts to collapse:

1) ask yourself a question: "What am I doing wrong? ";

2) start TALKING to your spouse (try to understand his/her inner world if you have not previously

 tried to do this);

3) try to do something unusual, pleasant for your soulmate.

But, unfortunately, if you realize that your energy is not suitable for each other, then, of course, you can try to develop your partner's spiritual level to match yours (if yours is higher), but

 it may not be very easy, but it may be close to

 impossible. Therefore, if you see that there is no result in the spiritual direction, it is better to part, then this is not your real soulmate.
