I don't think there's anything wrong with taking some time out from this. Perhaps a more laid back approach would work best, don't see it as like embarking on a total life style change but just a hard earned opportunity to take some time for you.

What doesn't get talked about a lot are all the good things about being single. Nothing i suppose can replace being with someone but you're certainly given a lot more freedom to do not only what you need to but what you want to do. If you try and let go just a little bit you might find yourself rather enjoying your new found independence. Even if that's a stretch, space in these sorts of situations are often a good thing - there are no distractions, no other pressing concerns it's all about you for once. Surely things can only get better?
