anxious attachment

does anyone else have an anxious attachment style? finding themselves not showing much affection during the relationship but once you feel threatened it may end being extremely expressive? i’m wondering how your experience with avoidant people has been.. i never understood them backing away until i really stepped back and realized how my behavior came off. my ex who i presume is avoidant due to past experiences told me he never felt cared for till something was going wrong & truthfully i can’t stop thinking about it because he’s right, not that i didn’t always care but i just didn’t show it. maybe i’m just not good with words of affirmation or something idk but there’s just such a distinct difference in me when i feel someone slipping away.. is anyone else like this?
