Its really important and equally hard to not go down the road of "What is he thinking". Once that game gets started in your head it takes on a life of its own.
Its so important that in this early stage you really come to terms with the fact its not ALL your fault, but you do have to accept your share of the blame. And get to working on your issues. Its also important to not mind read, and as you've probably read "Believe half of what he does, and NONE of what he says".
I know its nice having someone to talk to, with family members it can be a bit different, cause they don't want to see you hurt, they can give advice that's not always the most constructive. Its important that no one takes a side right now, she be as neutral but supportive as possible. Its not so important to get answers and as it is to just allow you to vent. Its such a fine line.
Understand your husband is in a fog, he's running, he doesn't care, he thinks these are answers to the problems. You cant fix/change what he thinks, just address yourself. Trust me, I know exactly how hard that is to do, especially after just a couple of months. Know that your issues go back many many months or even a year or two, so they obviously cant be fixed in a matter of weeks or a couple of months. Stay positive.
If money is tight, see if your local library has a copy of either divorce busters or divorce remedy. It gets you out of the house, and it doesn't get any cheaper than a 1.00 library card, or even go down and read there a little each day to keep getting you out of the house.
