So now that my SO sees that I'm willing to get a job to move he's saying that life's going to get "complicated" and that I've changed my mind so quick even tho I never even wanted to move in with my MIL to begin with. I don't understand why he doesn't want his own space when his mother is so controlling and rude. I feel like I'm loosing my mind everyday I'm here and stressing out. I swear this house is gross. Crickets get inside the house, flies that get inside from outside because the grandma has plants that attract the damn things, and then small roaches and HUGE roaches inside the house. I've never lived in a place like this. 😖😖😖😖
