It sounds like your DH is burning all his energy at work, and trying to de-stress with alcohol, TV, and sleep on evenings and weekends. It's understandable, and common, but not healthy, and I can understand the effect that this is having on you.
He's recharging his batteries with stuff that excludes you, essentially, and meanwhile your own needs for caring interaction are not being met - you too have your energy depleted by work and chores, and if what you need is to share some kindness and caring with a loved one in order for you to recharge, then the current set-up is no good for you.
Has it killed the love? Totally understandable if it has, in which case you do need to leave.
However, IF you think you still love and want him, and IF he is willing to take a long hard look at his work/life balance and make a lifestyle chnage, maybe this is salvageable.
You showing to him clearly that you are at the end of your tether and ready to walk as you sound in your OP may be the push he needs to take that long hard look and make some changes. Then again it might not: if he is to make changes, it will need to come from him, since he needs to feel truly motivated in order to change his life around.
I think you need to express to him clearly that you are ready to end it, as his current work/life balance has left you feeling unloved, unsupported, and not desirous to carry on. Then see if this is a wake-up call to him or not.
I feel for you, and wish you the best.
