I agree, if possible you move out for a while. Change of whole environment can really make a big difference rather than staying in the place where resentment has been building. I would add that I don’t think putting a time stamp of a return date on this is beneficial to you at this point.
It was my experience that when I took a break from my ex the first time, he was totally obsessed with when I was coming back. He was a “changed” man going to AA working with his sponsor etc. etc. all in a matter of less than 30 days. He sounded like he changed, his words certainly did, so I went back. That’s when the new cycle of break up – make up – go away- come here began. Talk about a roller coaster ride!
