I wonder if you should even ask her to the religious function in Boston, CL? Why put her in a position where you want her to say no? Do you think she may be offended if you didn't, at least, ask her if she would like to attend? Not asking may be a way of showing her that you are moving on with your life, unless you don't want to give that impression.
It is really good that you are able to say no to some of her invitations. It shows that you are your own person, and will react according to your own timeline.
As to temperaments ... personally, I think we go with who fits ours the best - whether it be opposite or similar. Some people who have very outgoing personalities, need a more introverted person to temper theirs.
Do you think your W is involved with someone who is more temperamental, and is possibly comparing you to him, and is trying to convince herself of the rightness of her choice? Just a thought.
Take care, and keep up attitude of perseverence, and patience.
