What's thicker - blood or ex-boyfriends?

I just broke up with my de facto who decided quite coldly that I wasn’t the one. I’ve been gutted by this. We’re doing no contact, but as long as he avoids me he seems to think it’s cool to rock up at the house we used to share and hang out with my brother (who lives with me), go golfing with him or surfing. My brother is really cruisy and thinks this is totally fine. Even though I’m crying every day about my crap life. K

Save your tears, Special K. I’d much prefer you cracked open a bottle of bubbly to celebrate a damned lucky escape from a guy who wouldn’t know sensitivity if it bit him on the arse. I mean, sorry, but exactly what part of, ‘You don’t want to be with me so that kinda means you don’t have access to my house and/or family’ does your ex not understand? Breaking your heart is bad enough, but to appropriate your family members for fun times and surfing sessions? He’s obviously clueless so I’m prepared to forget him and move on to your really clueless dude of a brother.
Does he not realise that blood is thicker than even the thickest ex-boyfriends? When I broke up with my last guy – the one who liked double trouble – my family tucked me under their collective capes, told him to talk to the empty martini glass and that was that: no tearful goodbyes, no maybe-see-you-rounds and definitely no friendly surfing sessions. I know the lines are blurry between blokes; after all, your bro’s probably thinking, ‘well, he didn’t break up with ME, so surely it’s OK for me to hang with him still’ but in the interests of family ties he needs to batten down the hatches and leave Mr Wrong where he belongs – out surfing that cold little world on his cold little lonesome and crying into his wetsuit about what an idiot he really is.
Of course, when you meet a guy who appreciates you, you probably won’t give two hoots about who Mr Wrong’s hanging out with, but until then, I’d give your bro a crash course in break-up etiquette.
Love, reality chick
