With time

I'm trying to be patient with myself. I want to learn to let things go. Saturday he called to tell me he had some of my mail and wanted to come by and drop it off. I told him to call me and I'd meet him somewhere. He never called. I messaged him yesterday about it, no reply, nothing.I really hate that he does this. But I want to let it go. Who knows why he forgot  about what he'd said to me. Who knows why he doesn't think my mail is important. I'm just trying to enjoy being in a great relationship. It's been almost three months, and things are going great. Sometimes I feel this guy is perfect for me. Actually, I felt very early on, but recently I've found so much proof of it.
