I agree with you, the tips in this article might be useful, or they might not be, depending on the person.

I experienced abuse and neglect as a child from my parents, which skews all of my feelings and expectations towards my wife. For example, she is very kind and loving, but this sometimes makes me feel anxious because I am not used to being loved and cared for, it's quite strange to me.

In a past relationship where my partner treated me with indifference, I felt strong feelings of love towards her because she was treating me how I was used to being treated - her indifference felt familiar, even though is was not a good thing for a relationship.

I'd say these tips are for people with a history of healthy attachments and loving relationships, not for people who have experienced abuse or neglect.
