<human>: Can you provide a brief overview of the text?

After years of different relationships with emotionally unavailable men, I've finally found The One - he is present, loving, ambitious, giving, motivated to take care of the relationship, deeply committed to making a success of us...everything I've said I ever wanted!  

The problem is, over the years I've developed any number of self-protecting habits that are now preventing me from fully engaging in this relationship. I'm now the emotionally unavailable one! For years I envisioned this kind of relationship, and this kind of guy, but now that I have it, I don't know how to exist within it.

I find myself defaulting to old behaviours like being withdrawn and distant, easily irritated by inconsequential things, not initiating sex, generally being passive, coasting along and resisting him loving me. I don't want to continue along this path because I'm seeing this guy as a gift from the universe and I really want to honour this precious thing I have.

I guess my question is, can anyone recommend intimacy exercises I can try to break down my walls? I sincerely want to give my guy 100% but my default setting is self-protection. What are some actionable steps I can take to make myself more vulnerable and create emotional intimacy between us?
<bot>: I've been in so many sucky relationships for so long, I have no idea what to do now that the perfect one has come along. Halp!
