Hello! I'm really horrified reading what you have been put through, and I understand the strength it takes for you to survive a household like that and be able to speak about it. Trauma faced at any point of time in life can have rippling effects over other aspects of life. However, there are ways to confront our demons and will need a thorough evaluation, and we will be able to manage some aspects with a short course of medications (if needed only) and plan a psychotherapy.
Secondly, if your partner clearly has stated that there is something lacking in the relationship it would help the two of you to sit down and discuss openly about it and be open to each other's views and expectations from the relationship and life as well. Hope this helps for now.
Next Steps
Seek a full evaluation.
