23M 25F: Feeling Stupid

TLDR: boyfriend takes his work frustrations out on me

Hi friends! I’m (25F) having some difficulties in my 3 year relationship right now and I’m not sure where else to turn to other than Reddit. My partner (23M) is currently working away. I came to visit him for a period of time. While he is working, I take care of chores, but I’ve been having a difficult time adjusting here because it is rather far from home (a different state). I’ve been relaxing every now and then. But typically I keep the house very tidy, run any errands via public transportation while he is working, pack his lunches and cook meals, etc. However, when he has a difficult day at work, he comes home and everything I’ve done (or didn’t do on my one day of relaxing) is criticized. I either didn’t put the shoe rack in the right position or I didn’t tidy enough. He asked me if I can manage everything like a “big girl” or if I need to be told what to do. He yells a lot when things don’t go his way, even something small. We’ve had issues like this in the past and they’ve been talked about. He was doing very well with everything however lately I feel very ‘picked on’ and criticized, regardless of what I do. I paid a lot of money to come here with him for this time. I am using my relaxation time to help take care of him. I understand he is stressed out because his line of work is stressful, but I am failing to understand how that then becomes my fault. It feels like I can’t keep doing this anymore or I’m going to fall apart. I have difficulty holding it together while he yells, even though he isn’t yelling at me. He can be very condescending toward me and I tell him this, he apologizes, but then it happens again as soon as he’s had a hard day. I just am not sure what to do in this situation.
