my boyfriend seems to think that it's ok to get so drunk that he can't walk every weekend...
For gawds sake lyndsey your Scottish !! I'm sure your Polish guy is no different to your previous Scottish boyfriends. The guy isn't doing anything that Scot's guys don't do at weekends, in terms of getting drunk.
As far as the b@stard bit goes, I won't comment since that is down to you to deal with.
