My Fault? Am I right or wrong? Please help :(?

ok..so about a week ago, my ex dumped me via text message. I was so hurt and sad. He didn't even have the to end it face-to-face. Anyways we ended it on a bad note. We were together for at least three months, but we weren't exclusive or anything. We met online and texted all the time. We've seen each other 4 times to be exact. The reason for the breakup was that I accused him of only wanting from me. After the 4th time of seeing each other he kept insisting that we have . I wasn't ready for that and that's when I accused him of just wanting . Was I wrong? He immediately got mad and didn't talk or speak to me te rest of the day. The next day he texted me saying it was over. Mind I tell you that we broke it off twice before,and both times he ended it with a text. I forgave him for both times which were not my fault. You see I live a pretty hectic lifestyle and warned him that we wouldn't be able to see each other all the time, anyways he kept insisting that I was blowing him off but I warned him before. That was the second time. The first time I didn't reciprocate my feelings to him so he ended it once again via text. But that's another story...anyways, I don't want to end things on a bad note and I was thinking of texting him. It's been about a week since, and I want to text him again saying that I don't want us to hate each other. Good/bad idea? and am I wrong?
