If you can't forgive your neighbor, can you love them?

   I know in life there are things that are difficult to forget; God knows in my past there have been many who have done things that were hard for me or hurt me - stories that deserve a book more than a paragraph.  But bitterness and anger allowed to fester can (and for me, for a long time, did) tear a soul apart.
   Love requires the ability to forgive.  If you can't forgive someone, can you love them as God says is the greatest commandment???

Forgiveness:

"And when you stand praying, if you hold anything against anyone, forgive them, so that your Father in heaven may forgive you your sins." ~Mark 11:25

"When they came to the place called the Skull, they crucified him there, along with the criminals—one on his right, the other on his left.  Jesus said, 'Father, forgive them, for they do not know what they are doing.'" ~Luke 23:33-34, 

“This, then, is how you should pray: “‘Our Father in heaven, hallowed be your name, your kingdom come, your will be done, on earth as it is in heaven.  Give us today our daily bread.  And forgive us our debts, as we also have forgiven our debtors.  And lead us not into temptation, but deliver us from the evil one.’
For if you forgive other people when they sin against you, your heavenly Father will also forgive you. But if you do not forgive others their sins, your Father will not forgive your sins." ~Matthew 6:9-15

Love: 

   "One of the teachers of the law came and heard them debating. Noticing that Jesus had given them a good answer, he asked him, “Of all the commandments, which is the most important?”
   The most important one,” answered Jesus, “is this: ‘Hear, O Israel: The Lord our God, the Lord is one.  Love the Lord your God with all your heart and with all your soul and with all your mind and with all your strength.’  The second is this: ‘Love your neighbor as yourself.’  There is no commandment greater than these.”
   “Well said, teacher,” the man replied. “You are right in saying that God is one and there is no other but him. To love him with all your heart, with all your understanding and with all your strength, and to love your neighbor as yourself is more important than all burnt offerings and sacrifices.” ~Mark 12:28-34
