Hi Marcel.
I think its excellent that your wife is at least in the first step and that is getting the support she needs for herself. Although whatever she is going through now, will not go away overnight, she is taking the necessary steps to heal and that is a very good sign.
It may seem dark and sometimes lonely for you and your son at this time, if there is enough love, you can get through anything. I have a 4 year old son and my boyfriend is in Iraq right now and has pushed me away. Each new morning, I rush to my email, sleep with my phone and think of him nonstop.
Its confusing and sometimes I don't know what direction to take. During these times, I do my best to make a happy situation for my son and do my own personal healing. Like walks, runs, parks, and a lot of yoga. Absolutely no alcohol I suggest, as it is a depressant. In everything I do, I have my boyfriend in the back of my mind, wondering if he is safe, wondering if he loves me, and wondering if his love will return to us.
I know everyone is going to tell you to take care of you and that's the only thing you have to at least remember to take time for you and your son as well as be a support to your wife's transition. Love her and be patient. Hold her and when she pushes you away don't take it personal.
She's dealing with her nightmares. I have ups and downs and am confused everyday. I send my prayers to you and your family. God Bless!
