are we all over attached

I get attached to people, I am not sure about places and things, but I am very sure that I get attached to people very much. I don't know how to describe it but there is always something deep inside that makes me attached, even when a relationship is becoming toxic in a strong way, I still don't want to lose them, and if it's all over, sometime later I think of going back to that toxic relationship, I make excuses but deep inside I know that is not a good thing to do, but sometimes I lose it... whenever I see something that reminds me of them I really feel hurt, I panic and feel anxious, sometimes I just connect a lot of things together and I doubt my choices, I drown... Maybe I know that whatever happens there will always be something left, something I can feel, maybe later it will turn into nostalgia, maybe I will miss them or maybe I will just miss the times? miss that there was someone filling this spot one day in the past? or am I just afraid, afraid of the memory, afraid of the wounds, I really have no idea but what I know for sure that being strongly attached is making it a lot worse for me what do you think? is this a common thing for INFPs? do you experience something familiar? thanks for your time and sorry for my disorganized writing have a good evening/day
