<human>: my current girlfriend of two years as a close relationship with her ex-boyfriends family. And she wants to go hang out with them (ex won't be present) me personally don't like the idea and I think is wrong and disrespectful. She knows I don't like it that's why she has not seen them since we been together but still talks to them biweekly at least once. 

She invited me to come with her but I don't think that's a good idea and it will be really awkward. But she says she's going to see them soon with or without me and I don't know how to deal with this. What would you do if you are in this position? Would you go? Not go? leave them? etc.

Could you distill the essence of the text into 1-3 sentences?
<bot>: would you be okay with your current boyfriend or girlfriend hanging out with the ex's family (if the ex wasn't there?)
