Any advice? Tips?

I just got into a new relationship (4 months now), lately we’ve been arguing like cats and dogs. I feel like from his side because he doesn’t see me often and it’s really because I’m spread thin while working full time and being a full time mom. From my end he’s not a patient person & when he expresses his frustration, it’s a build up and when he blows up .. it doesn’t come off too nice so I’ll react sometimes. He suggested that maybe we need to stop clinging to each other so much, we’re always on the phone with each other whether we’re at work or not if we aren’t with each other. Now we’re both in our feelings a bit (me moreso him) because that was a routine we created and suddenly that routine is broken. Any advice? What can we do differently? I love him a lot, when it’s good.. it’s AMAZINGGGG & so is the sex lol but when we’re upset with each other we will take a little time & come back to solve whatever problem it was.. I just want this to work so bad 🥺 & please don’t ask what we argue about because I don’t have an answer 😂
