Is it time to break up after almost 3 years???

Cheresh
Me and my so argue almost everyday over little petty things!! It's like we can't even enjoy eachothers company anymore cuz we will disagree about something I love this man with all my heart I know he loves me and will do anything for me but our relationship is on eggs shells and I honestly don't know how much longer it will last ... But I can't let go Ido why I just can't let go idk if I'm just comfortable or what a part of me knows that we won't last but i don't wanna accept it I can't ... Idk I'm just venting because we just got into a argument over him turning the tv 😑😑 I'm asking him why he keeps turning it he tells me I'm being overbearing I guess whatever I'm hurt cuz I hate arguing with him it really drains me Idk what to do anymore.
