Yeah, with all relationships really, friends, family, mom, dad, sisters, etc. I have big trust and abandonment issues. I think they go hand in hand, for me at least.
Being close physically and emotionally sends off huge alarms for me. So if I'm feeling wonky about breathing sounds or being physically/emotionally close, that particular day, I just hang back, but try to bake/cook him something I know he likes as a gesture of love so it won't trigger abandonment feelings in him.
I try not to push him or test him so much, and then I tend to be clingy as well. I guess it makes our relationship needlessly rocky, open communication helps calm the nature of the swing. With him, watching him work on the relationship as I was sabotaging it really helped me see he was different. We have our ups and downs, but I like to think we have more ups now.
I don't know how to make the abandonment issues 'go away' but realizing where they come from help lessen the push-pull effect on our relationship. We've been together for 12 years, married 10. We take it week by week, and try to make each day better. Certain days, or events seem to trigger, even though we know it's a trigger point, but communication has helped lessen the push-pull both in force and duration.
