I am of the opinion that you shouldnt jump inot a commited relationship on the heels of another. maybe you should talk to him more about that. besides, just because you put a leather band around your neck doesnt change anything.
I made that mistake with my first sub. she and i started dating soon after my split with my ex. i talked about collaring her. i think that put unreasonable expectations on us, cause she totally wanted it and i didnt understand the depth of that commitment.
