Why has my ex boyfriend texted me after 8 months of No Contact?

I got a text from a number I didn’t have stored in my phone today. I had a new phone recently so I don’t have a lot friends numbers…

They said they had two tickets to an event (one that I was very interested in) and asked me if I wanted to go with them, but as I didn’t know who sent me the text, I replied asking who it was. When I got the response and saw my exes name, I was surprised, but not too shocked. He sent me a friend request on Facebook a couple of months ago now (which I declined of course) so I had a feeling he would be in contact again eventually.

There was no apology or anything. I might have actually been tempted to go if I got a nice text apologising but he seems to think it’s perfectly normal to walk out of someone’s life without a word for 8 months and suddenly reappear without any explanation. All he could say was that he thought I would ‘appreciate’ the invite… I told him that I would appreciate it, but the problem is I’d be going with him. He said “I thought that might be a problem for you but the offer is there anyway” and then he went on to send another text saying “Oh by the way you don’t have to look around with me. You could totally go off and do your own thing if you want to”. My last text to him was “I don’t think so. Surely there are other people you can invite.” I don’t plan on texting him again.

He replied immediately saying “Yeah I can. That’s fine I was just thinking you might fancy coming. I completely respect the decision. Let me know if you change your mind. x” Haha, as if…

I’m wondering if he’s done this because he’s curious and just wants to see how I am. Or maybe he wants to find out if he can reel me in again? Or maybe he is just bored in his life?
