It is very helpful to explore and work through these issues however you can. Don't ignore it or the cycle will repeat. We are dealing with very subtle influences with origins that are not so obvious.
Even when our needs were unintentionally neglected, there is an impact.
If you are able to explore this via a therapist of some type, it would be most helpful.
I recommend watching Susan Elliott's videos on Youtube related to her book called "Getting Past Your Break Up" very very helpful.
