No ring?

My man proposed to me after a night of confessing his love. We don’t have much money and I never wore rings so he wouldn’t know my size. He said he would get a holder ring until we make more money. I wanted this 140$ one with our daughters birthstone… he won’t even buy it…. I told him I got sized at Walmart. He never asked for the size. He saw the one I wanted. Still hasn’t gotten it? But bought 100$ weed. I’m sad. My heart sank. I wish he would be serious. I guess not. I’m dumb.
