So sick of this

My husband and I always go through these phases where we don't have sex for days, sometimes weeks and I'm so sick and tired of it. He is always so caught up in his video games whenever I want to have sex and whenever he wants to have sex it's the middle of the day & our sons awake. I've tried several times to I initiate things between us but he just scuffs me off for his damn computer game. I'm so sick of it. I'm sick of being denied. I'm sitting here crying in my bathroom because we had a night of sex planned but I couldn't find the lube and he didn't care to help so I just said fuck it and gave up. I wish he would grow the hell up and take on some adult responsibilities. I wish he would learn to help out. I'm so sick of my marriage right now.
