What is your experience in dating with Fearful avoidant?

Mine in short: Fast connection, love bombing, moved together quite fast, lived together almost a year. When suddenly she started acting weird, exaggerating minor things or recalling things which i never did(I've started questioning my own sanity). Then she just broke up with me and moved out.

When i learned attachment theory and aligned her behavior and her past with FA traits it was 101% match.
