<human>: Condense the text into a few key points

I've been seeing my ex boyfriend from high school, for the last 4 months and in between the time from we broke up till now, we both dated other people. I broke up with my boyfriend of 3 years 2 years ago, and he broke up with his girlfriend of 2/3 years last November. 

While we dated other people or were single (it's been in a span of 8 years), we would always text at least once every other month or see each other around town and catch up. A few times while he was not seriously seeing this girl, we did occasionally flirt. Finally we realized our feelings for each other and are getting back together. But I'm a tad worried... While I was waiting for him to come back from picking up food, I went to grab a sweater in his closet, where I found cards underneath the sweater, from his ex girlfriend, and her running tag from a marathon she ran. I knew he had her sweater still in his closet and gifts that were intended for her for Christmas (they broke up before he could give them to her). I told him that bothered me so he said they were expensive gifts he didn't just want to waste and throw out, but he would if it really bothered me. As for her sweater, he said he would get rid of it. Within a month, he moved to a new place, so I assumed he got rid of the sweater and presents, and was hoping he wouldn't take the cards either. I know its normal to keep cards and notes from the past... but is it? Anyway, I ended up finding the sweater, the gifts AND the cards/notes. I asked him about the present and again he said he would get rid of it. He hasn't. He tells me he loves me, he's crazy about me and wants to be with me, and I do believe him....
<bot>: He's keeping/hiding the cards from his ex, sweater and her marathon tag. Am I just being a crazy girl and overthinking this, or is he holding onto something still?
