I responded on my thread, but just wanted to reiterate here. Proceed with caution. In the same way that it says here that when attempting the 180, we need to show consistency, your spouse needs to show you that he is committed today, tomorrow, in a week, in a month etc. It's not that I don't believe in forgiveness, but having read so much now about their "journey", they are living in a fog and their actions depend on whatever it is they are feeling at that time. Before he moved out, my H, cried on my shoulder and told me he wanted to have more "babies" with me, like more children would fix things. The next day he went back to ignoring me again. Another time, he came into my room (I think of it as my room now) and said "we were worth saving and maybe we should go away somewhere, just the two of us". When I spoke to him about it a few days later, he said "it is too soon" and went back to ignoring me.
So, by all means leave the door slightly ajar. But don't open it fully until he proves he deserves your forgiveness.
