Yes, that would be different. addiction is extremely damaging and can manifest in ways which are dangerous to the people around them.Whilst I firmly believe addicts need support and not isolation, I can see why someone would be cautious about being around them.That's very different to 'I don't like the fact they post pictures of themselves online'

I think you should go. It's one evening and will make your partner happy. Express any boundaries if she makes you uncomfortable and if she continues to do so, tell your boyfriend. Personally, I wouldn't continue to be friends with someone who intentionally broke my partner's boundaries. It's so disrespectful and it shows you what type of person they are.

I think you're being immature for not giving her a chance but he would being immature if he bruses off the fact she broke your boundaries
