Or are they ever a good idea? (Some non-essential details changed in case it outs me)
My BIL split from his partner of nearly 10 years around 2 months ago. It was horrible, he was calling in tears several times a week as his ex had been having an affair, totally devastated him. We helped him as best we could being the other end of the country from him (mainly relaying advice from MN about the script cheaters follow, which she did - to the letter :()
He was contacted about a week after the split by someone he vaguely knew asking if he was alright, offering a shoulder etc. A couple of weeks later, he phoned to say he had slept with her, it shouldn't have happened and he was going to apologise to her, explain he wasn't ready for anything. Fair enough.
Now, he has just told us that he is in a relationship with her, has stayed at her house for the past week and has met her children.
He is coming down for a visit in a couple of days, and OH is ready to tell him what a prat he's being by jumping in so soon, but I am a little more hesitant. We don't know his new girlfriend, she may well be a lovely woman and perfect for BIL (I'm assuming only good things about her).
I know he will ask our advice about it, because he thinks I am very wise and all knowing after using collective MN wisdom to help before, so I guess I am looking for some more wisdom? Should OH say his piece or not? Should we remain silent on the matter and see how it pans out?
I don't want this to cause any tension over the visit as this is the firt time we have seen BIL in a few years. Help!
