I need to know whats going on, because i don't know if im in the wrong

right

i live with my mum and my boyfriend moved in with us a year ago [he has never paid rent or anything] we have been together for 4 years

our house has been up for sale for a fair while and last week we sold it, tonight we had some house viewings and my mum asked if my boyfriend would mind not coming, he said yeah yeah fine and seemed okay....although i knew he wouldnt be, i was terrified about going home because i knew he would argue about it with me, and now it has just blown up in my face, hes saying that he wont help move anything because he is not 'a valued member of this house' but i told him that if we liked a house we saw tonight then we would go back for a second viewing with him, now he refuses to talk to me.

these kinds of things happen all the time, you guys will probably hear about them, so sorry in advance

I juts need to know if i am in the wrong, what shall i do, im in pieces yet again

thanks
