Eeeewww.... tis' how boys are.
And SO many of these things will happen...
Just tell her not to chase after him, to keep her identity, not to base his actions on her self-image.
He is a jerk.
They are common.... common as house flies.
She will find someone else.
This is ONLY a 6 month 'relationship" so far...
No guy, is worth... beating herself up over him.
Yes it hurts, yes its not nice, yes its sad.
But.... its not worth it.
Tell her... to just do her own thing. Do not chase after him. Do not whine/cry... to him... about it.
He is a jerk.
Is he the same age as her??? Regardless... this is an ADULT "boy"... and he is just not nice.
She will find someone else... who WILL respect her and care about her... and show it... properly.
This guy... is not worth it... not worth hoping for.
I have had those so called boyfriend types too. They are a dime a dozen. They don't care. They treat girlfriends like spent kleenex.
She will get over it... and be wiser for it.
No man... is worth.... destroying your own self-worth, for.
AND, playing games like that, with a partner... is so not nice. Thus, he is showing his 'character'... and why would she want a guy like that anyway?
This guy, is a DEAD-beat.... no money, no work ethic, a jerk, and jerks her around like a toy.... does she want to be a "toy"? I would think not.
all the best,
