Marriage trouble

My husband and I have been married for 5 years and the sex has never been mind blowing but over the last 3 years if I do t initiate it we could literally go 2 plus months without having sex. We argue about it all the time and I am almost at the end of my rope. He is not affectionate at all, we don’t cuddle or hold hands and if I don’t kiss him we will go for a full week without a kiss.My husband is an amazing man other than the physical issues, but it is taking an emotional and mental toll on me. And for the first time in our marriage I am starting to notice other men, I have not cheated. My husband has turned into a roommate and a bad one at that.

Just looking for an option.... Would I be happier married to a respectful man without having sex or single and able to have sex without hurting him.
