I posted this on another board but I don't think it was the correct place. So I'm sorry for double posting admins! I'm new... Please forgive me

When my BPDex and I broke up 3 weeks ago all of her friends texted me and said "We aren't even taking this seriously, this is just her July thing."
Last July, she got into a massive fight with her family and didn't speak to them for a month (She was also combative with me occasionally), the July before that she had a major eating disorder, The July before that she got into a physical altercation with a good friend... .Who knows the July's before that... .
Does anyone have experience in this? Does anyone know if certain months trigger rage and strange behavior? Should be bracing myself for her contact to me when her "July thing" blows over?
