mallyh: He refuses to play any type of board game - I think this is more because he just wants to play on his Xbox (I should of added more information into the opening thread, I was typing it on my phone though).

I might have to put my foot down, but how without making myself feel worse? For the people who know me, as some of you do (enough to be able to comment), I suffer from severe mental health and I do sometimes get to a point where I feel so low whilst being with them - not because I don't want to be with them but because I hate to see them arguing.
