Having an excuse for something can have many reasons.
The way the person behaves tells you its real intention and as you said is.. he wants to distance himself from you. This can happen often in life and is usual, just keep acting friendly on the same level as the distant person if you want to keep the contact in the future people can always change their minds.
Finally the decision of how you take it is up to you

Rough stuff but my advice is to not even bother with that. As hard as hell as it is that they broke up with you so - delete/block and spam if you can't do the mythical friends thing without wondering about a text back. They have your emotions on a string and they know that when they eventually text you back for whatever reason you will respond. I know I've been there - I was there recently, now I've decided to stop being a puppet. You can do it. They ended things remember that. Be strong.
