Never too late to grab some counseling help.
You can do it as a team, look up and really figure out the expertise of the counselor and read the real people reviews during a possible search.
I know you are muscling through your own way, and I respect that. I only throw the idea back out there because of how it helped us.
My wife's LTA was 4-years physical and 2 more emotional -- in all, the AP friend of the family was in our lives for a decade before she finally told him no for the first time ever when he reached out to get things going again.
So, I have an inkling of your pain.
My support system was limited to SI and counseling.
And counseling isn't an end all be all, it is just a way to safely vent and get some communication coaching.
Today, I do not wonder what my wife is thinking, she feels safe sharing her thoughts. And, if I still have any more than the 5 billion questions I have asked already, she is always willing to answer another question, no matter how far afield my thoughts go. This helped us a lot.
I also fearlessly share my pain, my joy and anything else in my brain with my wife.
Being all me, all authentic, every minute of every day, that helps me a lot too.
I like your update. I am glad you are learning to breathe again.
I hope your healing continues.
I hope you vent some more here when you need.
