my partner and i have been fighting for what feels like weeks. i've been going through such a hard down and i don't know why. so i've been snapping really easy and just being kinda mean. i haven't been abusive in any way but i haven't been nice. he's been saying he's tired of it and has come to close to ending it a few times. so i've been really on edge and kinda lashing due to fear of abandonment on top of my depression. 
  today i realized i couldn't fit into a skirt from last year and started crying my eyes out. this really set me off as i have an eating disorder. he told me he would help me lose weight and get healthier. minutes after he looked at these empty chip bags and said "wow that's a lot of bags" and it just really upset me because i didn't need to hear that at the moment. a few minutes after that he was taping boxes while i was putting stuff away. he kept asking for help and i was coming, just not fast enough for him. so he started calling me lazy over and over again. which pissed me off and i got really snippy. he got annoyed i was snippy and said "fine i won't help you lose weight!" and i told him i didn't need his help as i've done it alone before. and he said "yeah, you'll be puking in a week" referring to my bulimia. i told him to leave me alone and after like five minutes he pretended like nothing was wrong. being sweet and nice. which just really pissed me off because he was just so rude. so i really flipped out and he left me alone. he went downstairs and texted me "let me know when you're ready to see me. i love you so much." so i told him i will he when he apologizes. he texts me after an hour and says he's going to some party. so i go downstairs to ask what the fuck he's talking about. he's sitting with his mom and she's just fucking staring at me while he acts like an asshole. he just completely flipped from an hour ago and told me he's tired of this and i need to be nicer. and he just wants to hangout with his friends alone. it's not like an all guys thing. it's a party. and the hosts girlfriend always asks why he never brings me. i'm just really frustrated and don't even know how to begin to repair this.
