F*** up

So my friend got back from vacation about a month ago and she ended up hoking up with her ex boyfriend a couple of nights. They both wanted it. Apparently his girlfriend is pregnant and is having an abortion. But he won’t tell her he cheated on her he did say that he missed her but it wasn’t the same. The guys is claiming that my Bestfriend wanted them to be apart and just wishes they aren’t together.

Any advice I should give her?
