Kinda upset..

I'm upset I feel stuck I have an overall good relationship we just had our son 7 days ago.
Which is a key factor sorta...
Let's back up it may make sense..
I was before him beaten hit and abused I've had BFs who are immature throw tantrums throw things yell and scream.
I said never again I ran away from them and got myself to where I am.
I'm now with this man yes it is usually good but he has these tantrums and I've told him it scares me and upsets me..
He won't stop he slams doors screams throws his phone just freaks out.
Never hits me doesn't direct this at me..
But it sets my triggers off from my past and makes me angry and very sad..
He blew up again tonight I refuse to speak to him.
I'm fed up I've had enough.
I don't know what to do am I wrong to feel upset after more then 5!  Of these outbursts..
Over stupid shit btw not me just random stupid shit here's an example..
His stupid Galaxy 6 isn't working at all it won't work on wifi for or the 4g network we've gone threw 3 phones..
Now we just got a new refurbished one Friday and it is now shut off won't turn on is fully charged..
And he's flipped out big time I've just gotten so annoyed I dunno.. Wtf am I suppose to do talk to him again?
Or what..
