Am I overthinking it?

Heads up this question is kinda long, but I'm going to to shorten it as much as possible. My ex boyfriend and I were together for five years before he came out of the blue saying that he wanted to breakup mid February. Our relationship was great at first, but we started having issues with him not communicating with me as much, talking very negatively to me, jumping from job to job, and almost ignoring me.(I know I should have left, but I love him. We have all been a fool right?) I purchased a electronic item via a rental company with my ex under the assumption he would be going half with me on it needless to say that didn't happen and I was paying all of it even though after I graduated last may and moved back home I had no stable employment and he was working full time , but did not offer to pay. The next issue is the phone bill that we share. After the breakup I had already been unemployed almost 6 months due to not being able to find any job he said that he had no problem paying it. I asked him several time through the months. I even thanked him for paying it acknowledging that was something he did not have to do. He then start paying my netflix that we were sharing as well. Fast forward to now I told him I was moving because I had found a job and now he doesnt want to give me my electronic, he now says he wants to pay for that too, and threw it in my face that he paid for my phone,and netflix. when I finally told him he could have the tv as long as he paid it he also told me he was moving to the same state, but two hours away. Am I overthinking all of this? Am I wrong for thinking something is up with all of this?
