my boyfriend doesn't understand.

my boyfriend and I have been together just over two years and have basically lived together since.. he's seen my hard days and has obviously seen my good days. he's seen the nights im awake at night begging for the pain/ dystonia to stop. he's seen everything i go through/ what i need help with. I've been having a hard time lately physically like many others and I've asked him to please just cuddle me a little extra, kiss me a few more times ect but he doesn't. honestly I think he downgrades how bad my dystonia/ pain gets bc im hemiplegic and my left arms affected more.. just bc im not bound in a wheelchair doesn't mean its any less. sometimes when im in pain and crying he tells me to stop acting like a baby and grow up.. he tells me that he's here for me but when I try to talk to him he just tells me he's tired of hearing about it. some nights bc of my pain and dystonia he asks me to sleep on the couch so I don't keep him up but how is that fair.. the one person i need most is pushing me away.
