I've tried to convince him into either couple's therapy or individual, but he always says 'why do we need a therapist to have us communicate when I'm standing right in front of you'. I can not give him an ultimatum to be in therapy as I would not be able to follow through with breaking up.
We've both been tired lately as we just brought home a puppy 4 weeks ago, and as a result he's easier to trigger into yelling (out of stress, never with anger or insults.) Before getting the new puppy, I'd regularly been getting ~6.5 hours of sleep, and him usually 8 (I drive far for early shift, he works from home at 9.) Since getting the puppy though it's been more like 6 for me, and 7 for him.
My mom is getting to our apartment this evening for the weekend. Last night he was wanting us to get the apartment tidied up some, but I'd passed out on the couch at 10. When I woke up at 11, he'd already gotten a lot of everything done, but was starting something that I was supposed to have been doing. I'd came in there and was saying 'babe that was my thing', and he just started yelling for me to go away. I'd simply tried to ask how he'd gotten so worked up about me falling asleep, and he just continued yelling. I'd lost interest in doing anything else to help for the night after that and went into the bedroom to cool off. I think I fell asleep a bit longer, but after he'd came in there and showered I went to go shower, and we didn't speak the rest of the night. This morning I was leaving for work, and we'd hardly said a couple words. We've agreed to put off this fight till Monday when my mom leaves, but till then I don't know how I'm going to appear to be in a good mood anyways.
The last time he was yelling was because instead of taking off my shoes literally on the doormat, I wanted like 3 steps of space into the apartment to set my things down. Later that night he'd came to me and apologized, agreeing that he was overreacting.
Usually once every couple weeks he will get over stressed enough and yell about something, but will usually come apologize after cooling down. I don't know if it could ever cause me to lose my love, but I do know I'd never be strong enough to break up with him over it. About a year ago I had broken up with him because we fought too often, both cried in my car for hours discussing it, and he convinced me to get back together after we'd been separated for maybe a week.
TL;DR: My partner was yelling at me last night and now we are fighting with my mom coming tonight. I'm worried about getting tired of having him yelling and ruining my love for him.
