Still confused

Hey remember last thursday when we were sitting on the grass in the park and you told me that you try to forget about your past, but when you talk to your brother he always reminds you of it,, And it hurts? Well that's sort of how i feel with you. When you and her go home together on the bus, or get the same things to eat or have inside jokes or you say exactly the same things to her as you used to say to me when we were together, i'm reminded of the past and it hurts. I can't explain why, but it just does.
Thanks for being so patient with me for the past couple of days. Things have started to get better. I feel like such a failure, but i swear i'll try harder to let this not affect me--just please don't give up on me.
