Into my shell

It would be so very easy
To retreat if things went wrong
So very easy to return to 
Feeling hurt, weak: not strong
If we were to end this
If our connection were to sour
How would I cope?
How: deal with separation: hour by hour?
Would I retreat? Return: revert...
Pull my neck in: yes; back into my shell?
Revert back into seclusion
Retreat back into my usual hell...
