"Maybe I am over think this" Strange that you should say so !
It is estimated that the human brain produces thousands of separate thoughts, associations and memories every single day. Most of these thoughts are without significance; they come and go without us noticing. Some thoughts, however, attract our attention.
This is precisely what you are now going through. Perhaps, deep in your psyche you have recalled the association with this lady and now you are deliberating what to do.
Sometimes we can procrastinate too much and overthink the situation.
Just go for it - at best you may find the get together enjoyable and glad that you met again.
