Hey Ats. I'm sorry you are going through this right now. I remember how painful that it. I was doing the same thing in April. It is terrible. And we had everything together too, (except what I think he was hiding- and I didn't push for him to disclose everything- long story, just be careful and remember- BELIEVE NONE OF WHAT THEY SAY!) including rental units and business accounts.
Chances are, he does not want to lose you, that is scary for him, but he feels he needs to do this for some reason. It's so hard to accept that. I can tell you this, once you get past this part, it will get a little easier. It does not mean everything is over and there is no hope. I just thought in my head, I would give him the d and he could check that off the list and hopefully see that was a mistake. I wasn't going to really let it change what I believed.
It is really difficult going through what you are going through right now, and my heart goes out to you. It is only temporary. Keep in mind that whatever the outcome, it will get better! This is another bump in the road, but it is not eternal.
Allow yourself to feel and acknowledge your feelings. Then move through them onto the next.
Your kids will be OK because you are strong, you are fun, you are great! You will be their rock and provide love and affirmation to them. The will grasp onto that and appreciate it. They may appear to take any frustrations out on you, but that's because they feel safe with you. They know your love is unconditional.
