Thank you for requesting me.
The best way to address any type of transference of unresolved issues to current relationships is to address the original cause of the problem, in this case your relationship with your mother.
Whenever someone has a dysfunctional relationship early in life with a parent, there are unmet needs that do not get fulfilled. The strong desire to be loved, cared for and nurtured are within every child. When a child seeks to have a parent fulfill these needs and is rejected, the need stays as the child grows up to adulthood. The adult then tried to find relationships that meet this need, usually ending up in dysfunctional relationships that not only do not fill the need, but cause more distress.
That is why it is important to go back to the original cause and resolve it. You did mention working on issues in your past. Did you feel you made any headway? Were you able to see a therapist? If your therapist did not help or you did not see a therapist, it would be a good first step to find a someone to talk to. They will be able to guide you with insight and resources and help you resolve your feelings. To find a therapist, you can search on line at http://therapists.psychologytoday.com/rms/. Or you can ask others for a referral, such as your family doctor.

It depends on how much you feel you want to end the relationship. It probably is beneficial for you to try the couples therapy but only if you feel that the end result, should it be a good outcome, would motivate you to stay in the relationship. However, if you feel that no matter the outcome you still do not want to be in the relationship, then it is best to end it now.
Yes, some people can stay sober without help, but it is rare. Drinking involves so many aspects of a person life that they almost always need support of some sort, even if it is just a sponsor, a very supportive family and a therapist.
The personality traits of a person who uses is going to be the same sober or not. There needs to be a serious effort made to change this aspects of their personality if they are to be completely successful.
You cannot be the only support for your partner. Because of your emotional involvement, you are not as objective as a therapist or other support and she may not take your interventions as seriously because of it. And unless you have had a history of using, she can dismiss your interventions as "you don't understand".
