Hi, I'd like to help you with your question.
Yes, your feelings towards your partner most likely is because of how you were treated growing up. As you pointed out, both of your parents had emotional issues. Your mother was narcissistic and your father emotionally distant. You did not get the care you needed.
Children need parents that provide a balance of comfort, security and discipline. You were not able to get that because your parents were damaged emotionally. Instead of providing you with what you needed, they took out their dysfunction on you and blamed you and used you. As a child, you got the message that it is not safe to be close to people because they will hurt you emotionally.
When you sought out men who were emotionally distant, you were just seeking what you were comfortable with. It was too baffling and confusing emotionally to be with someone who treated you differently. But now that you have understood through therapy that you had a pattern of choosing men like your father, you have consciously changed it. That is good. But you still need to address your feelings about your father and the damage he, and your mother, did to you. Because you are not there yet, you remain emotionally distant in your current relationship.
You can return to therapy if you feel it would help. Taking a look at the damage you feel from the lack of love and caring in your childhood would help you understand and learn to love yourself. Accepting that you are not to blame for your parents problems and that you are worthy of being loved are some of the things you could work on.
You can also address this at home. There are several books that can help you gain insight into your feelings and help start you on the road to recovery. Here are some I recommend:
Adult Children of Abusive Parents: A Healing Program for Those Who Have Been Physically, Sexually, or Emotionally Abused by Steven Farmer
Toxic Parents: Overcoming Their Hurtful Legacy and Reclaiming Your Life by Susan Forward and Craig Buck
If You Had Controlling Parents: How to Make Peace with Your Past and Take Your Place in the World by Dan Neuharth
Children of the Self-Absorbed: A Grown-Up's Guide to Getting over Narcissistic Parents by Nina W. Brown
It would also help to involve your partner in your recovery, if he is willing. Not only would it give you the chance to have his help in understanding how to be more emotionally involved in your relationship (by modeling his behavior), it would give him a chance to share your journey and become closer to you in the process.
I hope this has helped you,
