I once read something that I thought was really true for M/F breakups and is probably going to apply here.
After a breakup, the guy starts out feeling amazing, flirts with loads of women, enjoys the classic 'single life' but the sadness about the end of the relationship catches up with him over time.
After a breakup, the woman starts out completely depressed, really in her feelings, struggles to adjust, but over time manages to improve and return to happiness. It's like they go opposite ways.
Obviously not a hard and fast rule but one I've observed and experienced a few times - and seems very similar here.
