The minute you're single, it seems that certain 'well-meaning' chums can't wait for an opportunity to drag out the clichés - "Plenty more fish in the sea" or "You've got to get straight back in the saddle" and my personal favourite "You're not getting any younger!" Since when has 'singlehood' been stigmatized to the point at which your nearest and dearest can't bear to think of you without some bloke hanging off your arm?!
Being 'single' isn't an illness you should be 'cured' of as soon as possible, nor does it imply you're utterly 'unlovable'. It just means that at this moment in time you're enjoying your own company, probably recovering from the trials and tribulations of a bad relationship and (for once) you're getting used to being YOU again.
If and when you decide that you're willing/able to begin searching for your next 'plus one' is entirely your own choice. Personally, at this moment in time, especially after my ex sent me stroppy texts for refusing to allow him to keep his credit cards registered at MY address three months after he moved out, Hell would need to be substantially sub-zero before I'd consider walking down that particular road again.
