Bill, only a few people ever see us while they are still in the physical. Why? Well, there are a number of reasons.

Here are some...

Their attention is on other matters.

Their spiritual frequency is not high enough to perceive beyond a very limited spectrum of what is termed "visible light".

Their rigid belief systems censor their perceptions of reality. Children, for instance, are far more likely to see spiritual phenomena, because they haven't yet decided that they don't believe in such things (they haven't been told not to yet, in other words). Belief itself can grossly limit perception. Negative beliefs reduce one's ability to "see".

Angels will appear to people sometimes in moments of tremendous stress and/or great need. The stress itself proves sufficient to heighten perception, and the need may be there for an Angelic communication of some kind.

There has been no particular need for you to see an Angel lately...therefore you haven't seen one. Whether this will change depends entirely on you.

Many people do see Angels when leaving the body, at what is termed "clinical death". This may happen in your case. Let's wait and see.
