Had some time today to investigate my issue. I have a new MC on the bench but will deal with that later.

I bled the front brakes, drove the car, no difference.
Then I bled the rear brakes and pedal as it should be when new!

Absolutely no leaks, fluid level was were I left it last year. I feel that I didn't bleed enough fluid from the rear that any fluid in the MC or ABS area should have made it all the way to rear and out the bleeder. So where does that leave the air getting into the system?

Just something to think about. Not sure a new MC will do the fix but will get to that point.
