Well... the other day I was packing up stuff to move back home

. Anyhow, I got to my photo albums and started packing them up. My boyfriend grabbed one and started looking through it. A few minutes later he looked quite upset. I asked him what was wrong and he said he was upset that he saw pictures of my exes. And that it was MY fault he was upset because I had reminders of past relationships. I was shocked!
I don't take many pictures so I keep all of those that I do. His take is that since I've broken up with these boyfriends I should throw them out. That since I'm with him I don't need reminders of other people.
What most upset him was the pictures I had of one of my exes who was abusive. I was with this guy for 3 years... the 1st half was absolutely wonderful and we went on a bunch of fun vacations together (where the pictures were taken). and the 2nd half of the relationship was horrible. It's almost like there were two versions of my ex. I keep pictures of him because I like to remember the good times... because there were some really great times!
I am not sure what to think of the situation right now... what are the rules on keeping pictures of ex boyfriends...especially if marriage is in the picture? I asked my Mom and she only dated my Dad, whom she married so she said she never had that issue and couldn't help me out.
Also, I told him that I forgive my ex for what he did to me not for him... but for me. I feel that forgiving someone takes away thier power, and not letting something ruin your life. It's in the past and although it was terrible I don't want to forget it. My boyfriend became very upset and yelled that what he did is "NEVER FORGIVEABLE". He has been depressed and pouty whenever he is "reminded" of my ex he won't look at me or talk to me. It makes me feel like he's angry at me for getting into an abusive relationship.
Any comments or suggestions would help greatly! Thank you soooo much!!!
