I'm mad at my girlfriend for dumpster diving
Why are you mad at her for dumpster diving? Also, I thought you two are married?
Not yet, but we have been in a relationship for a long time
Have you talked to her about why she is dumpster diving? It can be dangerous going through the trash as there are unsanitary and unsafe things in people's trash. Maybe you should let her know you are concerned for her safety.
She says she needs to eat and I want to prove that she doesn't need to do that.
Yeah, I think so too that she needs to find an actual job to fund for groceries. Dumpster diving is really dangerous and can get her quite sick! You really need to try to convince her away from it before she gets hurt.
