Seriously Help!

Have you ever loved someone so much that it hurt so bad when you've almost lost them or if you even think about losing them? But you also know you need to let them go because they hurt you so much emotionally? Here is my story: I feel all of the above. He hurts me because I go to see him all the time wether it's for 2 hours or more or less even though he lives 30 minutes away from me. Recently he hasn't come to me at all, even on his days off..... I've been using my gas to see him almost every night wether it's at his work or at his house and he never comes to see me at work nor my house anymore...... I need advice ladies, please help me.
