It sounds like your husband visited and wanted to reassure you that he was ok and very much still alive and with you.
I had a somewhat similar experience a couple years ago. We had a friend on this site, Romain, who ended up getting sick with and dying of cancer.
A couple years or so after this, I was meditating and unexpectedly Romain popped into my awareness and gave me a hug, which I felt/experienced in a physical like way (I could have sworn I felt his whiskers on my face briefly).
I asked guidance about it afterwards and was told that during the meditation, I was raising the vibrations of my entire energy system, including the physical body, and Romain in turn was slowing down his vibrations some, so that for a brief moment, we synced up vibrationally (aka resonated with each other strongly), and thus I experienced the contact in a very visceral, physical like way. While I had never met Romain in this life, we seemed to have a deeper Soul connection, which is partly why I think he visited me though I didn't consciously seek or ask for the contact.
I know that you desire more contacts with your husband, and that is very understandable, but I would advise to let these things happen naturally and not to become too focused on it. This can actually block/hinder such contact. Also, your husband wants you to live your life. You will be fully reunited when you pass on, but meanwhile, you have things to do here, which is why you are still here. He left because his work/lessons here were done and now his work/lessons are in the nonphysical.
Also, when you open up self in meditation, it's important to pray/set an intention to only open up yourself to and communicate and commune with helpful, loving, constructive sources that have your best interests in mind. This is a practice that everyone can benefit from, but especially those whom are in a more vulnerable state.
Anyways, I enjoyed reading your heart warming account of contact with your husband, and feel for your temporary loss. Just try to keep in mind, it's only temporary. In terms of the Soul, it's a blink of the eye, though it may seem much longer to our personality self and minds.
