Just looking for outside opinions on a situation that bothers me but I'm not sure I can do much about.
Soon to be DH has a best friend of many years standing (I've also known him albeit much less well for years before I met DP).
Unfortunately, the guy is a waste of space. Nearly 40, dead end admin job despite being an intelligent guy, perpetually broke, always involved in some drama with some woman or other (often more than one at a time).
He consistently lets my DP down with plans, is often downright rude to him by text or in public, has (long in the past) shagged a very recent ex-girlfriend of DPs, frequently asks to borrow money etc. Happy to be bankrolled for drinks / dinner when he 'needs to talk' or 'can't afford to go out until payday' but never ever returns the gesture. Texts DP his relationship dramas at all hours of the day & night. In addition to all this he drinks too much, too often, in inappropriate situations and is frequently an obnoxious and attention seeking drunk - this isn't really an issue for the friendship but it doesn't help matters.
From the other side, DP moans about him but just sits back and lets himself be a doormat and I can't understand why, except for him being far too kind to be mean to anyone, no matter how much they deserve it. He doesn't have loads of friends but the rest are all really good guys.
I absolutely don't want to be the Partner that dictates who he can and can't be friends with but it makes me so mad & defensive to watch him be walked over again and again and keep going back for more like a puppy
It's getting harder to bite my tongue.
WWYD in this situation please?
