It’s really nice of your boyfriend’s mom to take you guys in. It sounds like you appreciate that and try to show it by helping her out around the house. It seems to me that the main thing for you to figure out right now is... are you guys just going through a rough patch or is there a pattern to your boyfriend’s behavior? People have rough times sometimes... we all go through hard times throughout our lives... but ultimately you need to be able to communicate and work together for a relationship to withstand those hard times.
