I think I made the wrong choice

I think I have made the wrong choice with staying in my marriage I have had the opportunity to end it twice in the last 4 years once i had asked him to leave due to drug use and the second time he moved out because I wasn’t doing what he wanted (honestly I have know idea what happen that day ) but couldn’t let go i wouldn’t say we have the best relationship or are the happiest people our sex life is great we can never agree with the way each other parent the children we don’t really fight but also don’t really do anything together we never dated and never have alone time he is always playing his games while Im either reading or doing something with the kids I’m bored but also feel if someone come alone and showed me a good time I don’t know if I would stay loyal (I wouldn’t have sex with someone else But I would get emotionally attached ) every time me and my husband fight or have a disagreement he tells me he is going to move out and honestly I don’t care anymore I love him but I don’t know if that’s enough anymore I do everything for him make his coffee cook dinner clean up he only does washing and the odd dishes as the kids wash up and the yard work o honestly don’t think he would last with out someone to look after him but I want a husband not a man child
