Dear Jordy,
It's wonderful that you have someone to love you back unconditionally.

Jordy, spending weekend with Jordy sounds a wonderful idea

. I love doggies!
But also do try to expand your social group. When your family fails you, you do need another support network. You can try spread your weekends to different stuff........anything that gets you away from your brother, unless he enters therapy and mends his ways.
good luck!!
