I need advice, i would really appreciate if someone could take the time to help me in this situation?

My ex of nearly a year split up with me 6 weeks ago and i havent seen him since. We had a long distance relationship and initially it was over a text message on my phone from a guy friend about a job that he didnt know so I understand why he was upset. We still stayed talking as friends although he was sometimes blunt and things were kind of icy. We had a fight on friday over another girl I thought he was seeing and he said he wasnt happy with me and how I always cause fights and its who I am. I admit we did have the odd scrap but never screaming at each other and no more than other couples but we always went to bed happy and resolved them quickly. in the weeks leading up to the break up I was on his case a lot as it was our 21st 2 weeks before we split and I wanted him to come to my party but he couldnt as he had a match (hes a footballer) I do understand how important his career is but at the same time i was very hurt and I got in to my head he didnt care so I supposed I pushed him, because I wanted a reaction and wanted to see if he cared. I was immature and just wanted attention really. He text me Saturday night and said he was sorry for hurting me how he loved me and really missed me but couldnt be with me as he wasnt happy and i wont change. I promised him I would and admitted I was immature and only realise this now and how all couples go through this but if he loved me he wouldn just let go without trying and he said its the right thing. He popped up on FB chat yesterday morning and asked me was I ok? I said yea and was he and he said ya then I said I was sorry for making him so unhappy and that I missed telling him my stupid stories and he said I miss hearing them aswell. I text him earlier and told him all i wanted to do was hug him and he text back hours later and said me 2 :( , he text me later then and started a conversation putting x's at the end of messages and then told me missed kissing me and i said i missed snuggling into him and he sent me an unhappy face i told him i loved him and he told me he did 2 but i didnt text back. I spoke to his mam this evening and she told me he had a fight with her a week ago and they havent spoke since (they are both very stubborn) so could this be the reason he isnt asking me up to his house? Why would he be speaking to me like this and telling me how much he missed me if he didnt want me? what is your opinion? please help
