If you aren't emotionally healthy and ready for a relationship, then you do him a disservice.
You don't strike me as not emotionally healthy and ready for a relationship, you strike me as scared. And that's normal!
I'm so much better than I've ever been, but dating was scary. Scarier still once I found a guy I actually wanted. And I still have little panic attacks about it that come solely from me. From my fears that no amount of IC and healing are going to cure. Sort of like if a horse bucks you off, a little fear is going to remain until you get back in the saddle again and see that you aren't going to get bucked off again.
In my current relationship, we've had some miscommunication issues b/c of both of us having knee jerk reactions. And we're having to talk through those. And I'm real upfront about what my fears are too. So even though there is some of that legacy shit there, messing me up today, in real terms it's producing a better relationship than I've ever had before b/c stuff gets talked about. And RESOLVED. That's mind-blowing to me.
It's okay to be scared. And it's ok to explain yourself, where you're coming from. If he's the honest person you think he is, he'll account for your fears and it will produce better communication between the two of you.
