Do you think she was trying to make me jealous?
hard to say. an engagement is big news for anyone, so i dont consider it unreasonable let alone necessarily malicious. it sounds like she considers you a friend and keeps you updated on some level. if she knows youre happy and in another relationship, i dont see why shed try to make you jealous. its possible making you jealous was an underlying motive, whether it was conscious or not is impossible to say.
