Hello nb408,
I am really sorry that you are going through this right now. It is never fun to have strong feelings for someone and to not have them reciprocated. When I was dating I had that happen to me and hated it! As I was reviewing your thread, it occurred to me that this is a lot like the story of Jesus...
"He grew up before him like a tender shoot, and like a root out of dry ground. He had no beauty or majesty to attract us to Him, nothing in His appearance that we should desire Him. He was despised and rejected by mankind, a man of suffering, and familiar with pain. Like one from whom people hide their faces, He was despised, and we held Him in low esteem. Surely He took up our pain and bore our suffering, yet we considered Him punished by God, stricken by Him, and afflicted. But He was pierced for our transgressions, he was crushed for our iniquities; the punishment that brought us peace was on Him, and by His wounds we are healed." Isaiah 53:2-5
Not that I would equate anyone to Jesus, but Jesus was completely "despised and rejected by mankind" and yet He went through the most painful experiences I can think of to show His love. If this comparison seems a little off key, take a couple of hours and watch the movie "Fireproof" (that is if you have not already seen it).
So, it is hard to love someone when they don't love you. I don't know if you have had the chance to read the book by Gary Chapman entitled "The Five Love Languages", but if not I would highly suggest it. Dr. Chapman has determined that there are five love languages and everyone has one or two primary languages in which they prefer to receive love. Usually, they tend to express these languages as well to others. The love languages are:
1. Gifts (G),
2. Quality Time (QT),
3. Physical Touch (PT),
4. Acts of Service (AS), and
5. Words of Affirmation (WA)
They should be self-explanatory. There are two important things that I have found with my wife of 13 years. First, it is critical to "speak her language". When we first met and were married, her love language was QT and mine was PT and WA. I would always give her a hug, hold hands, and put my arm around her while telling her I loved her, but I was a work-a-holic. I thought I was showing all of this love to her, but since I wasn't spending QT with her, her love tank was on empty! Once I learned this, I adapted and things got real good really quickly. Four and a half years and four children later and I had to learn the next important thing about the love languages: sometimes they change over time or with a change in situation. Now that we have four kids, my wife has no time for quality! So, her love language now is AS. The more I can help her, the more her love tank fills up!
I know that this may not help you in your current situation, but I hope that it helps you in the future. Please know that I am praying for you.
God Bless You,
Kevin
