Undiagnosed ADHD and threats of divorce

My wife left in January, very suddenly and became very cold.

for the past 6 months she has either said has been ambivalent about whether she wants to come back. In the lows she has said some very hurtful things - "you're not my wife" "I don't love you like a wife". In the highs she's spent more time together as a family with our son, said she was trying and gave elements of what now seems like false hope.

She has impulsively paid a deposit for divorce then immediately put it on hold. She has put our family home up for sale then blocked viewers.

we are back in a cycle of her saying it's completely over...

im so so exhausted. I love her but can't keep going on like this.

 

anyone?
