Boyfriend was too busy?

We have been together for 9 years but recently he's been too damn busy to do anything with me.He didn't call. He didn't text. He didn't put any effort into the relationship. I tried to talk to him abo ut his schdule the week before last but he couldn't make it. The next week he didn't contact me at all. He's basically had time to do everyting last month accpet spending time with me.All i wanted was one day out of 30.So,on Sep 21st I broke up with him in a text message. He would not return my calls to his cell for 2 weeks. I feel bad about breaking up in a text message but there was no other way to contact him without being creepy. Should I feel bad?
