amartin, two counseling sessions are not going to solve much, but at least she and you are going to couples therapy. If you have had only 2 sessions over the course of 61 days, then my first thought is that isn't often enough. Can the two of you go weekly? Maybe the first thing that could be negotiated, with the help of your couples therapist, is that you will both commit to 10 sessions of marriage counseling over the next 3 months. During that time, neither of you will file for divorce or threaten to file for divorce. This will give you some space to work on your issues.
It would probably also help if she wouldn't talk about her marriage problems to her parents, since they are so negative. It will be hard for therapy to work if she gets constant negativity about the marriage from her parents. She needs some space from the naysayers to give therapy a fair chance. This is something that could be negotiated early in therapy also.
It sounds like you have an individual therapist also? (if I am reading correctly?) Your T can help provide support. Perhaps some friends can help too?
