It's just fine to ask. You never get anywhere without open communication.

Were I in his position, I wouldn't be able to resist a good couch snuggle one night (that would melt me like butter in any case). Perhaps a back rub and a drink before said snuggling to make him more willing?

At this point I'd say just letting him know that you still have strong feelings for him would be the best choice of action, and then take it from there. You aren't wrong to ask for more if you feel he's not giving his all. The way I see it is that, if a couple is not ready to take the next step, the man should give at the least 85% of his affection to the girl. If the couple DOES plan to take the relationship further, the man should give no less than 95% of his affection, and should he go below that, apologize and make it up.

Believe it or not, men are almost never as tough as they make themselves out to be. We men are like puppies in a sense. When we know they are loved, we will do almost anything for our girl, and we'll beg for more all of the time. Sometimes all it takes is a brief spat and then forgiveness (on both sides) to smooth things out. Just give him what he likes, like his fav food and drink or something like that, and then talk with him.

We humans are like wolves, we're incredibly social creatures, and when we don't share enough social interaction, it tends to show most in our relationships, the same way it would show in a pack of wolves.

I hope this helps.
