How can I save us ?

How can I save my relationship? We’re 21 & 22 and have 2 under 2 .. we’ve been together 6 years ..

All we’ve been doing lately is fighting and getting irritated with each other over everything.. it’s not money stress, we’ve been very blessed with good jobs but it seems like for him it’s all about work, it’s what he does even in his free time with us he’s checking on work on his phone and that’s what bothers me .. I’ve talked to him about it and asked he spend time with us during his free time but it just doesn’t happen ..

I just feel like we’re roommates raising kids and occasionally having sex

I want us to work .. I want our spark back .. I don’t want to give up yet

I just don’t know what to do 😔

** I’m not upset he works to make us money I just get upset when he’s off for the day or weekend and spends it working on his phone and not with us .. I’m not trying to seem ungrateful **
