Why has he sent me this?

Why after 8 weeks of no contact from my ex has he sent me this? Background: we were in a relationship for 5yrs, friends for 5yrs before we got together. We were living together for 4.5yrs and had a house we both were on lease for. I got a message from “the other woman” 8.5 weeks ago to tell me he had been cheating for over a year and the day i got the message he left and moved in with her. He took 6 weeks to move his stuff out but never said a word to me in that time even though I know he had been crying for over a week, and told my close friend he knows he fucked up. I know the OW has a massive trust problem with him and has to track his phone every time he leaves house, and has already kicked him out once since he left me and won't let him see any of his friends. So why now send me this message? Im still struggling with not having him in my life and i still love him. Im of the opinion that he can write this to me, but words need nothing without action. Words are powerful, and I’m really struggling with his absence in my life. Is this his way if saying sorry/goodbye - or something else?
