I tend to agree with Sandi. I have a similar situation with family this weekend, albeit it's my family's home. Sill debating my response to it. In your case, it isn't neutral territory, it's HERS. If OM *is* there, I see too much chance of it erupting. A best case is you walk away REALLY hurt, and even sicker than you already are. Another party for you and your son isn't going to be normal, but it will be especially for you 2.
