Thank you for taking the trouble to post this chart, sorry to ask you to do so much work!
You write this is about your friend and her boyfriend, not her husband, but you apply the arabic part of divorce. I wouldn't give much weight to this.
If they are together and the question is about them separating, I would look for signs of separation between them. The current status is together, we want to see if something changes that.
Saturn we saw is strong in her own sign, and close to the end of the sign. She is sitting on her own ascendent, and not going anywhere. She is not making any moves.
He is moon, in her sign of Capricorn, an indication that he cares for her, and is under her influence. He is in her 12th house, so cannot express himself, and is closed in, and doing things she is not aware of. Moon does approach a square with Venus, who rules his 3rd, so he may be going online and doing things behind her back in that way.
However, moon approaches retrograde mercury first. Mercury rules the turned houses 5 and 8, which represent romance/children and sexual attraction. He may be fooling around and having affairs she does not know about.
So, do either of their significators relate to planets in a way that indicates a separation or a break up? No.
Moon separates from a conjunction with mars, so in the past they may have been arguing, perhaps about his infedelity.
But I don't see them separating.
