My boyfriend has a problem with smoking weed

My boyfriend told me he'd start an argument if I went home to pick up my weed to smoke. I cannot believe he would say that. I'm aching for weed right now how selfish can someone be. It's not like I'm pushing it on him, it's for me and I bought it with my own money. He's essentially saying to choose him or weed. I can't believe people these days!
