How can I get my husband to be more intimate?

. I've tried bringing this up with him, we had a big argument over it and things did improve for about 2 weeks, which were 2 fantastic weeks, but now it's back to how it was before and it's horrid.

I'm always the one initiating things with my hubby for intimacy, of every kind. It's so incredibly demoralising and I feel as though he's not interested in me. I've tried bringing this up with him, we had a big argument over it and things did improve for about 2 weeks, which were 2 fantastic weeks, but now it's back to how it was before and it's horrid. I almost wish things hadn't improved because that way I'd not know he is actually capable of that level of intimacy. I really need some advice.
