I actually looked up several articles when you mentioned "preoccupied attachment"I would read Sue Johnson's work before coming to conclusions. It's true that you don't want a hyper-critical or judgmental partner. With that being said, it's actually frequently the avoidants that wind up getting mixed up with us pre-occupieds. They are drawn to us because we pursue and no one else will. They don't mix with their fellow avoidants actually. Then we go through a long cycle of torture with them.
Johnson's work is worth reading.
And, yes, definitely keep being loyal and caring you. Keep reaching out to others. That's a good thing.
