As someone who recently ended a 3 year relationship, that's excellent advice, TA. Taking a break from FB really feels great, and I've replaced the time I would spend screwing around on FB (or chatting with my gf) with doing little house projects (cleaning the garage, changing air filters, etc.). Or actually picking up a phone and calling people I haven't chatted with in a while. Or even taking up new hobbies or old ones I've neglected (wanting to get back into drawing, game dev, weights, bike riding, and DJing). Or getting ready to schedule my dream vacation, without being encumbered by my ex and her neediness and whinyness.
Sure, it sucks a bit when everyone is out with their SO's on Saturday night and I'm stuck at home by myself, but I've been so busy lately that just staying in and playing some backlogged RPGs (or reading a book, or practicing my sketching) is refreshing.
It's weird, I feel so much different after this particular breakup. Got over the girl MUCH faster than usual, am not in such a hurry to jump back in, or hell even start dating. Even though I'm 34 and the only non engaged/married one in my social circle, and after previous relationships I fretted that "nobody else is gonna go for someone like me, I'm too much of an unattractive, socially awkward nerd with weird-ass interests". I dunno what it is, it could be that there are too many little things I want to do first.
