i want to forgive and forget!

Me and the love of my life had gone thru some horrible times. We broke up because i felt like we needed to. Well in that time that we were apart it didnt help us at all it just hurt us bad.. I did something horrible and so did he..just he knew aobut mine and i didnt know about his till a year after getting back together and after him being mad at me and not being able to trust me for months the truth came out about him. Well its now been 6 months and i thought i had gotten over it but every now and then i think about it and it gets me angry but seeing that i already told him im over it i have to make up excuses about why i dont want to talk to him or why im in a bad mood..i just want to be able to be one of those people who forgives and forgets!!
