yet when he's feeling down and his bpd is bad it rises back up.
this is important:
BPD is not something that comes and goes. it is a set of maladaptive personality traits. it is a world view. it is a way of seeing oneself in relation to others.
Ive never said anything to him about commitment or wanting to put lables on anything but in his head its obviously an issue.
you may not have directly mentioned commitment or labels. sometimes the little things we do send signals.
I wanted a bit of emotional support from him
...
just to let you know I already like you too much
...
I replied that I was annoyed he'd started this back up again to waste my time if he didnt want anything from it.
all of these things signal that you want something deeper.
(he's 15 years younger than me)
he pushes the issue away until he senses that you want something deeper. he likes you, but hes signaling that youre pushing at a faster rate than hes ready for.
it may be that hes feeling insecure about the age issue if hes raised it several times. its hard to say.
the hard part, the real trick, when these things happen, is to listen (not react), and play it cool.
