Lola,
Mixed signals are common within the MLC; because the MLC'er really doesn't know what he wants; and so it is one thing, one day, another the next.
Should I email him and say a one-liner like "I'm here if you want to talk by email or phone. I will listen and I won't question you". Should I send that? or it makes me seem weak?
I wouldn't tell him anything at the moment; let him come to you; I believe he will when he needs you; and most likely not until.
In the state of mind he's in, he may interpret your email as pressure on him to talk; in other words he will see the "opposite" of what you are saying..they are like that; masters of the twisted word and action.
It is better to stay silent; and wait to see what he does; and in the meantime; get your focus OFF him and onto you; getting on with your life AS IF he's not going to continue with you.
Besides that, he won't trust what you're saying; they never do trust the LBS; again, it's the state of mind they are in for the time being...so; although you can do whatever you want, I'm advising you to wait until he contacts you on his own.
On top of all this; the crisis working on him is WHY he is what he is at the moment; and if you try and talk to him, he will twist everything back on you; and you don't need that.
Again, get on with your life, take your journey to wholeness and healing; more understanding will come as you walk your path to the end.
