Bright, Life Twists is right about the communications situation being fairly normal. Sometimes they will pop out and text/email and other times, they just completely disappear until they want or need something from you.
Freedom is a total fixation for them. If they can have their freedom w/o pressure from the spouse, then they usually go along their merry way and will not push for a divorce. However, if you push the issue, divorce will come up and it's their only "excape" from what they think is holding them back to living their new life. Sometimes, after a divorce, they want to be friends immediately and then there are those who need plenty of time for the tarnish to set in on their "new lives" before they realize that they want to be friends w/us...but I caution the readers...friends to them doesn't have the same definition as what we would classify as true friends. Whatever should happen, things will and do work for the best. I didn't think my situation would work out, but it did and I am enjoying life w/o the worry of what he's doing, who he's with and what expenses will be coming my way that I would have to worry about paying because of his spending.
As for posting, that's up to you. But keep in mind, many of us read your postings and sometimes we don't post because we do not have anything to offer at that time. In my case, I sometimes think you are just journaling and I step away until something you post sends up a red flag. As Life Twists pointed out, it is more important for you to get it out in the open as it is for others to comment. I do want to add one more comment, posting here is a safe environment, whereby no one is going to take your postings and run to your h and tell him what you said or doing.
Sit quietly, the answers will reveal themselves when you least expect them to. The past is gone, the present is a gift and you need to focus on today, allow the future to reveal itself when it is ready.
