The risk is the reenactment of the original wounds that created your attachment style in the first place. The opportunity here is for deep healing for both of you.
Wherever you are on the spectrum, if you are serious about this relationship, I would enlist the support of a great couple counselor. I do not do this, so ask for recommendations and check out what is available in your local area.
If you would like to learn more about this relationship dynamic and how to work with it effectively, pre-order a copy of my upcoming book ‘Heal Your Anxious Attachment’.
Love to all,
