<human>: She has been having her fun in bed with a couple that has a young child (non penetrating kind of fun, apparently). They are close friends which apparently makes it ok.

She hasn't had a BF before and just did "what felt good" with that couple. 

I find this really difficult to deal with since she wants to keep seeing them (minus the bedroom activities). For me, this is extremely difficult to deal with. It feels like she's hanging out with her ex, because they are such good friends. She has recently slept over at their place, with another friend (f).

I consider her past behaviour morally unacceptable and I wonder about how she will behave in the future. I'm not sure we should stay together. She is otherwise really nice and we have a lot in common but I find it difficult to deal with her past.

I know different people have very different ideas of right and wrong bug I find her morals fucked up. What's your take?

Give me a shortened version of the text
<bot>: My GF has been having sexual relations with an older couple and wants to keep hanging out with them and it bothers me.
