Seasonal changes?

[Vexed]

Has anyone else noticed seasonal changes with their BPD relationship?

My BPD exgf would break up with me like clockwork every April.  She seemed to go through a period of inflated self esteem and high energy during spring/early summer where I would be devalued and she would run off to find new guys and new fun; going out every night, finding interest in things she had thought was dumb, etc.

Then three months later when her birthday rolls around she would recycle me by offering to take me back (definitely not offering forgiveness) in exchange for me doing something extravagant for her birthday.

[AskingWhy]

Vexed, seasons do indeed have physiological influence, so you may be observing this.   Perhaps rather than weather, maybe cyclical events could be influencing her behavior, too?

Birthdays (and the anticipation of gifts) may also be a part of this.  My H's uBPD/uNPD children (while in custody of his uNPD X W) did this to him all the time.  They would blackmail him for something (plane tickets or gifts), then cut him off for months at a time, refusing to take his desperate phone calls.  It was humiliating to listen to him leave voicemails sucking up to them.  When holidays like birthdays or Christmas approached, they would come back and butter him up.

Your BPD X GF sounds a lot like one of my H's Ds.  Whatever captured her interest depended on which man she was with at the time:  sports, hobbies, lifestyle, etc.

I know my H's dysregulating also is influenced by hormones (thyroid, adrenal, testosterone) and the treatment was, if not dramatic, observable.  H is less moody and less volatile.
