I agree. I myself have gone through things like this and endured the pain when I had to break away. I can honestly say I was better off for having let the person in even though it did not work out because at the time of letting them in I was not in a good place and happy for the love they offered (also, they had some unusual qualities that helped me so much that, in retrospect, it was worth the pain it cost at the end). By the point at which it was clearly time to end, I was in a much better place to do so. Plumtreeblossom seems far more poised than I was, however, and it makes much more sense to be choosier.
