Ending my almost 8 year relationship

I'm really thinking of ending my relationship it just seems like we argue over stupid stuff and the same stuff over n over again n I'm just really ried of it. Tired of it always seeming like it's my fault that I dont change any thing for him that I dont touch him we dont have sex i dont tell him I love I never stick up for him that hes never right that my jokes aren't funny n sometimes mean that after I had our daughter its like he doesnt exist so on an so on. I love him but I can't deal anymore he says it's been like this Almost 2 years. If I'm that bad then why the f*** is he still here he knows where the door is. I'm just scared to end I dont like confrontation and I dont want to hurt him I just want to be free n be myself again he came into my life when I needed him I was on the verge of living in my car but I think I've out grown him. I need advice on what to say how to end it. He doesn't believe in breaks either u want to be together or not.
