Communication is key

Yep, it really helps.

Honestly, I try to always do this. Just say what's on your mind. Make it easy for your SO to understand you. I also warn him when I notice that I'm becoming unreasonably grumpy, and try to keep him out of my grump-radar lol.

Me and my gf do this but instead of "I need attention" we just text "love meeeeee"

My partner has a similar method. When he wants attention he lies down on top of me like I’m a mattress

wifey and I just behave like big cats. whenever one needs attention they just move in close and snuggle silently for a minute. Then we stop and talk about it. If we're texting it's just a sad emoji, a - sort of - cry for help, and the other immediately calls.
