Let someone in

There was this man who wanted me in his life and I wanted him too. But, unfortunately I was not free, and he tried too hard to show me that I was not the only one he was interested in. Further more, we where so different ,but instead of embracing the differences, we showed total disrespect toward each other. I liked that this man was so different then I am, although this could be challenging for any kind of relationship even the friendship one. I know that deep inside he cherished and loved me, even though he could not understand me.
What do you do when faced with the situation like this? When I became Christian I understood that everything what happened to me is an act of God, and that He will never put me through something that I can’t handle. I don’t know if through all this I became a better person , more tolerant perhaps, or I closed my heart even more.
