I'm not sure I have any suggestions for this but I definitely relate. I tend to be very attached to some figures too. But I've always wondered if it's wrong and I'm terribily ashamed. This is the reason why people in my life think I'm a cold person. I'm just really really shy. And I'm fond of my therapist but I'd rather die than tell her. I'd feel small and stupid (I don't mean feelings are stupid, it's just my issue) and I don't want her to laugh at me and my feelings so I dismiss them. I constantly look for signs of rejection and abandonment to "keep myself down to earth" and be prepared and try to anticipate people that will eventually leave keeping them away, but I also want constant reassurance.

If it can help, I usually spend a huge amount of time trying to figure out what caused me to take distances or be bad to someone. I write it down and try to develop alternative options for the future - when I have time. It helps sometimes and makes me feel a bit more in control of my emotions and reactions, I was told it will be way faster and automatic after I practice it a bit.
(Yes, I am this bad to people I love).
