Confused am I morally wrong?

Am I morally wrong for not wanting to accept my ex's apology? I've gone through so much hurt and pain with him. Some people say get over it but that's easier said than done. I wouldn't say that I'm holding a grudge its just that I'm so sick and tired if being the nice person all the time and always so forgiving just to be walked on all over again.

I've always been taught to treat people how I want to be treated and to always be nice and to forgive. I don't like him and I take his apology with a grain of salt. Does that mean he's the bigger person because he apologized and wished the best for me and my kids regardless of what he did to me?

I'm having a hard time dealing with this and I feel like I shouldn't e-mail him any pictures because first I have a restraining order against him and I don't want that to back fire on me should we have to go to court again. Second when he e-mailed me with that apology and asked for pictures he didn't even ask if she needed anything or how she was doing so I feel like he doesn't deserve anything. Its not like he left on good terms. Am I wrong for feeling this way? Should I forgive and be nice anyway based on the fact that we have a child together? Even though I've forgiven him countless times before just to be made a fool of and be shitted on AGAIN??? Thank you all for your support with this.
