<human>: Summarize the given text in a few sentences.

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.
<bot>: would you be okay with your current boyfriend or girlfriend hanging out with the ex's family (if the ex wasn't there?)
