Hi Cph73,
I know that it is tempting to tell your son that you suspect he has Bpd because you want him to get the mental help that he needs but It should really be left to the professionals when he himself identifies that he has re-occuring problems that effect his r/s with others.
For me my udd's secrecy was also big issue too and it has been that way since her early teens. She is now 32yo. A lot of what I learned about the things she did in her teens was often only after the fact and some of the things she did then I would have been jailed for as an adult but luckily for her because of her age at the time they didnt press charges but it has left her with some lasting repercussions that she doesnt know that I know about.No details of her life have ever been shared. Even all her pregnancies (3) I have learned about through other people and when I have asked her she has denied.
Im sorry that you are already feeling anxious about your sons visit. What helped me when I felt that about spending time with my udd was to break the day up. Sometimes 10mins was long enough to feel the tension begin to rise so I would often take a break and go off into another room to do something else or be around others. For you this could be perhaps offering to take turns walking his dog if he brings his pet with him.
I think also having other guests there could also take the pressure off you. My udd has always been close to a particular family member and has really done well in family gatherings if this family member is there as I think she has felt more relaxed. Another time the family member was not there and she ended up starting a physical fight with another family member and attacking me when I tried to break it up.
I also think that other guests can also more effectively steer the conversation away from the topics that get your son fired up, and as your son is a heavy drinker I would make sure to only have a few alcoholic drinks in my home and the rest low alcohol or 0 %. Fingers crossed he wont even notice it is low or 0% if he has already consumed a lot already.
