Girlfriend keeps trying to control me, help?

hi, my girlfriend has lately opened up and said she is sick and tired of my actions around the house, and outside of the house, im a west ham fan, and my son has also become a big fan too, she gets annoyed at stupid things such as me and my son lounging around on a sunday in our west ham bathrobes, i told her it was a sunday, time to relax, when she heard me and my son were thinking of going up to the tattooists to have ''The HammerS'' tattooed into the back of our heads, she went beserk and stopped speaking to me, she says im taking it too far and i need to chill out from football, me and my son have a season ticket to the games, any we dont go to is put on the 52 inch plasma HD television, the other day i re-decorated our room with west ham wall paper and west ham bed set and she went beserk again, i try to do something nice but i just get stabbed in the back for it, her tart of a sister seems to think that im going crazy and dragging our son down, i dont really know what to do anymore, i've tried everything i can, i need help with this situation, thanks
