Is this trauma?

My partner and I met when we were 18. When we first were dating, everything was good. As we got further into our relationship, I realized how bad his anger was when it came to his stupid video games. He’d throw and shatter his remote, punch or kick holes in his wall, and destroyed a desk he had from punching it. I stayed tho. I got pregnant and slowly things got better. Once my daughter was born, the violence stopped. He never hurt me or anything. But even till this day, 2 years later since my daughter was born, every time I hear him suck his teeth or whisper yell out of frustration when playing, I’m brought back to those moments. The moments of me sitting on the edge of the bed silently sobbing and scared with our dog hiding under my legs scared too. She gets scared now too. Even the slight raise in his voice has her walking away to find me. I feel my heart drop every time he plays. I get so scared that maybe today will be the day he just has it with the game and throws something, though I know he wouldn’t. I always take my daughter and dog out to the yard so we don’t have to hear him. I hate feeling this way. I hate that stupid game. I’d prefer him playing cod with his friends than that stupid fucking game. It’s his stress reliever so I feel like I can’t tell him to stop playing. And I don’t want to talk to him about it bc I feel like I’ll seem like im overreacting and being dramatic. I have therapy tomorrow so maybe that’ll help work through this. He plays every night. Even when im trying to put our daughter to sleep and she’s fighting me because she’s distracted from the tv light. I feel so resentful towards him right now. I used to get excited when he’d come home from work but now that this game came out with a new version, I know he’s gonna get on right away so I hate when he’s home now because it’s like he’s not even here.
