i (25 F) being ignored and pushed away by bf (27 M) due to work stress

we are not broken up but something went wrong at my boyfriends job last night and he’s taking the stress out on me. when he’s upset, he shuts me out. i tried to be there for him last night and he was receptive. i thought everything was going to be okay. he was in a good mood this morning and had plans to get coffee but something switched. his mood completely changed. he snapped at me when i asked him what was wrong and at me saying “i’m not frustrated with you” “leave me alone.” i just started crying and told him to take me home. he started driving erratically and at one point parked and got out of the car. i exited the car and asked his mom to come get me but he ended up coming back around to take me home. we haven’t spoken since. i tried to reconcile with him after several hours of isolation but he didn’t want anything to do with me. he just pushed me away.

for context, this is a pattern of his where he shuts me out and ignores me whether he is upset with me or someone else/situation. we have plans to get engaged and married. we’ve been together for 5 years and live together. i don’t have much support as i only have one close friend ong the state im living in and all my family members live in other states.

i really don’t know what i want to do. i’m completely heartbroken. i feel like im going through this alone. i’m anxious for what’s to come. i know that this is unhealthy and still don’t know if this will lead to a break up or if we’ll make it work. i just want whatever is going on in his life to resolve itself and for him to be happy again. i also want to be with him.

TLDR: should i give him space and just ignore him for the time being
