Marriage sex problems

My husband and I have been having a sexless marriage. I’ve expressed my needs, which is to have sex at least monthly but preferably once weekly. We’ve been married almost 2 years and I planned our late honeymoon in a beautiful hotel.

He declined sex for 5 nights out of our vacation, including the night that was my birthday. I was so hurt but didn’t want to fight on vacation. Finally we had sex on our last night there but it definitely seemed like he really didn’t want to.

Now he’s laid off, one of his excuses was always that he was too tired after work. Well now he has no excuse, he stays up literally all night watching YouTube and playing video games and will not get into bed until after I fall asleep because he knows I’ll ask for sex. Why is he like this? I’ve talked with him but he honestly doesn’t care.

Oh and also we’re both in our 20’s so I don’t think it has anything to do with him not being able to.
