Tired of being unappreciated

Christina
I go to school full time semester just wrapped up I have a 3 and 4 year old at home and my fiancé works full time about 60 hours a week. Today he felt it necessary to make a point that he's tired that the house is a messy and so forth just yelling at me basically making me feel like I'm worthless and lazy. I was taking 5 classes and busy with school work every night while dealing with two little ones with no help from anyone else plus dealing with first trimester of pregnancy most of the semester the end got much easier but anyhow. I don't know what to do I just feel really upset and that he never has anything nice to say to me just always wants to bring up everything I do wrong. I'm really tired of it 😣
