Sounds like you may at least need to take a step back for awhile, protecting your daughter in every way is your top responsibility. And if you are seeing such big issues now I respect and agree with you that pursuing marriage with this person ( without things getting better first) is not a good idea. Marriage is a big,special, and hopefully permanent, commitment- so it is very important to take the time to choose who will be best for you to spend the rest of your life with, and be a good example and influence on your daughter. I feel for you and can only imagine how you must feel
