Hi Anna,
I'm terribly cynical of others. I don't expect that others without PTSD would really get what I'm going through. I also don't like to talk much about my self in front of those others, cause often I have been going through hell: e.g. the family:"what have you been up to"; me: "oh just been going through hell and back"-- that usually doesn't fly so well ;-).
Some strategies:
1) You can plan in advance, what are "safe topics for you to discuss" and "what are topics you want to stay away from". I don't find it safe at all discussing my PTSD to non-PTSD sufferers, it's like leaving myself wide open to attack (and it can hurt a lot more, and their hurtfulness can also re-trigger me). Identify safe subjects, positive things, e.g. a recent trip; a recent concert or show; funny movie; gardening; cooking. . . whatever feels safe, and not too personal where it could hurt if it were attacked.
2) Practice of "Active Listening": I've discovered that most people are quite content to talk about themselves. This is a little skill I've developed. I keep myself on the questioning side, they have to answer ;-); I've learnt expressions like " so you're saying. . . that's really interesting. . . what about. . . how is that for you. . . ". I can keep them going and going ;-). This is a skill that can be learnt via "assertive communication courses"
3) Non-Verbal Communication: learning to smile and learning to have eye contact. Easier said then done, it may take practice. I used to work in retail, so I had to learn how to pull that off. I try to generate a sense of self-confidence, from deep within, like at my belly chakra, feel happy inside-- actually abdominal breathing technique is a good practice ahead of something difficult for bringing out confidence, steady boundaries, I've discovered this recently. Generate the happiness and chanel it outwards.
4) Draw up a Safety Plan: Quick escape ideas if it's getting too tense and you need a break. For example, I worked on a safety plan in preparation for seeing some family in which I expected there would be some conflict. I called a crisis line, and talked it out. They gave me something useful, like saying that I need to go to the store to buy some aspirin. "But we already have aspirin" and I could say, "no, I'm sorry, it's not what my doctor recommended for me" or "that brand upsets my stomach"-- "I'll be back shortly. . ." . . . and you could get your husband to drive you there, or you can walk to the store, or whatever, but it provides an opportunity for a "time-out" and to practice coping and grounding skills, uninterrupted. You could even have a few for an escape, "I need to use the phone to check in with someone, could you excuse me. . ." and "I'll be right back". . . (and go ahead and take 20 minutes if you need it ;-) )
5) Don't take it Personally: Recognize that some people are just hard to please, and will find fault in us, no matter what we do or what we say, and just be okay about that. Remind yourself that the visit is short (don't plan long visits-- if they're out of town, also plan or say you have a plan to also reconnect with some friends, or something).
Just some ideas, maybe others here will have feedback on this, what works, what hasn't worked. . .
