Sad and Hurt

Im so freaking sad, hurt, upset these days I can't even function hardly. My whole life I've been with this one person nobody else! He lied and cheated on me and is trying to make it seem like its my fault im the one to blame for him cheating! Im trying to forgive make it work trying not to split up our family but he doesn't care obviously I've caught him still talking to the girl he cheated with multiple times! Its clear to me he doesnt want me. He has breaken me down to i am nothing! I spent 5 days in the psych ward because of all of this! I have a few issues he knows about and doesn't even care! Like my anxiety is at a all time high im sad I've pretty much lost everything because of this and im constantly being blamed. Idk what to do i just dont want to feel like this anymore!
