When Ginger said it gets harder and harder each time, what came to mind with me was PTSD. Not that breakups are likely a true PTSD type thing but the compartments of that include the repeated exposure and in that case, things most certainly do get harder and harder each time because we are sensitized to it and our brain builds it up and up and up. We then relate the current pain to the original PTSD trigger and therefore confuse the two. So, 25years, you are correct in that the actual break up after only 3 months is not that big of a deal and prior to the PTSD triggers it would not be, but our brain confuses and melds the two to where the recent breakup FEELS like the original. The more it happens, the harder it gets each time.
I'm sure this is partly the reason I am how and who I am today. I know darn well that a breakup after three months would not be anything like my BD coming up on 12 years ago now - yet my brain would relate the two and at least the risk is there for me to go into a depression like happened back then.
Does any of this make sense?
