<human>: Can you condense the text into three sentences or less?

My boyfriend's parents are divorced, and, of course, there's some animosity and ongoing tension between the two sides of the family. His cousin and I thought it would be nice if we could get everyone to come together for the last holiday (Thanksgiving) before he leaves for basic training. It would be nice to send him off knowing that he's more important to his family than their bickerings. 

I spoke with his mom today about his father, and ... it wasn't nice. Minor assault, cheating, lying, stealing, etc. I take what she says with many grains of salt, and I've certainly heard some stories about her, too. But it's always bothered me that my boyfriend tends to like his dad because he's "cool" (funny, chill, etc) and sometimes ignores that he's unemployed, lazy, immature... think the archetypal 40-something failure. Apparently he doesn't think the Thanksgiving plan could work out cause his current wife wouldn't like it. 

Personally, I am the type who tells their significant other everything that's going on. As such, it's hard for me to have this (very affecting) information without telling my boyfriend about it.... it almost feels dishonest. But it seems like an awful thing to have on your mind right as you leave for the military... so what should I do?
<bot>: Boyfriend's about to go to basic training and I've heard some deep family shit from his mom. Do I tell him the truth, or keep it to myself for now?
