She seems happy on social media but her public music profile has songs with lyrics so eerily specific to our breakup and so depressed-sounding that it's hard to believe she's really moved on. It's been 4 months and we were together 3 years. She was devastated the day of the breakup but has been acting happy since within a few days of the split. She says she hopes the best for me and she's dating someone new (very strong signs it's a rebound). What's going on?
