Infuriated!!!!!

Okay so I let my boyfriend use $100 because he was dirt shit poor, and what does that moutherucker spend it on? WEED. I can't help but to feel used. I gave it to him because he needed gas and I didn't have change, so I told him to keep for the week till he got paid, I didn't think he'll use me to support his habit, I thought he respected me more, guess not?
