Betrayal is always as much of a shock to the extent that initial love comes as a surprise...And a better question is why would you want to do without love? Not loving, closing yourself off from the possiblity of being loved, is a slow death of the soul. An infant, if well fed, and all physical needs met, except for that of human touch and comfort and love, will suffer a syndrome known as "failure to thrive"...I think of it as "baby depression", and if you think about it, adults will do the same. We need the love and comfort of human presence. Which is why, with as much joy as I have found in this little box, even though filled with wonderful people, with comforting words, full of caring--not once as it ever held me--my only complaint, I think.
And as to how to learn to do without it...smile...seems to me, that the minute you think you can do without love, it comes along...but keep in mind that people grow, they change, and not always at the same pace. So embrace love while she's there, like the surprise of an orchid in bloom in your garden. And throughout the cycles of seasons, tend to the garden. And yes, sometimes you may have to mulch over for a hard winter...but keep doing the things that enrich the 'soil' of your spirit. Come spring...turn it all over and start again. And that old love? Turn that over too. I like to think of it as really good fertilizer...grin.
