Any stalling, or worse, attempts at reconciliation are red lights for you to put a stop to seeing him until he is officially, legally single. If so, that tells you that he is willing to work on disagreements as well as letting you know that the divorce was not a rash decision.
Here is a checklist: You must be definite that he is actually getting a divorce and has not just taken a few weeks off from his marriage to "find himself" or "get space." Are papers being filed or served? Any reports of progress are a green light that he is headed in the right direction as a possible partner for you.
If his discussion of the divorce is a one hundred percent blaming of his soon-to-be ex-wife, take a step back. If, at the core, the problem with his wife was a drug or alcohol problem, she may be responsible for a big part of the breakup, but he may have developed co-dependent tendencies.
This means that he needs to be part of a relationship drama instead of part of a relationship.
He says he needs his space and he is up and down with his emotions. Let him talk and let him settle his business and give him his space without pressure and guilt. I do indeed feel that he is backing out of the relationship --tonight when he texted me he used my first name and not the usual "sweetie". Take deep breaths and allow yourself to cry for awhile. If you take care of yourself, you will be stronger and can better handle what happens in the future.
I am deeply sadened and feel I've done something to cause him to want to end this relationship. I would think he is going through reality phase of a very difficult time. Lovingly give him his space and let him work his man thing out. We have hardly spoken since returning from a vacation that ended with him cancelling our valentines plans. For example, if he needs someone to talk to, he may just turn to you again. Well it has been a week since my relationship ended and I am still crying.
