seperated a year

[hanging in there]

I'm really trying this NC since the last meltdown I had Sat, when after a day of casual texting about his day I get a text that he is tired of after talking for a week it always ends in a fight and he is not coming home. Mind you there was no fighting that day. I think he was drinking. At first my reply was okay. Then it went down hill. I replied with pouring my heart out and telling him how I would not give up on our marriage. This is after the week before I told him it has been long enough and I wouldn't waste anymore time on this. I need to stop the flip flopping but how do I state that while I am open to working on the marriage I cant wait forever for him to come home even though I would probably wait forever for him.
It has been 2 days of NC between us and my heart is aching to wish him a good night. In the weeks before we were at least talking as friends but with all contact being started by me.

Neither of us has filed any paper work or consulted an attorney that I know of. Part of me wants to maintain contact to work on the friendship but the other part says why he makes no effort for the friendship and is still contacting her and I should go dark since he has made it clear it is over. Because other times he shuts down completly and ignores all texts and calls.
