Many of us have been exactly where you are right now. The confusion as to why someone that claimed to care so much would seem to easily disregard your feelings. It can hurt and even cause us to go into denial not wanting to accept that maybe the things that a person said and the things that they do conflict with one another. Any person can easily say the words, "I love you". But to actually walk in love towards another person is a completely different story.
Two things I would recommend you consider:
One is to consider what Jesus would do and how He would respond. Let Him be your role-model in this and ask the Holy Spirit to lead your actions.
The other is something my mother told me years ago. It gave me peace and I was able to move on when I knew I had done all that I should but that I was just not being received with thanksgiving. She told me to simply respond, "You do not want what I have to offer. I wish you well."
You have to remember that you are considered a blessing of the Lord. In a likewise manner, your affections should be received with honor, praise (not in the worship sense but edifying sense... for the religious critics), and thanksgiving; a grateful heart.
Read Proverbs 5 (Ok... that is more than two things... lol)
I hope the best for you in your current struggle.
