To feel hurt at this

Guy friend was going through a tough time and would text me daily.
He met a new partner four months after being devastated after his wife left him for another man. Now on several occasions, he has said 'Sorry, I thought I had replied ' in response to my texts which he replies to a day or two later. All he seems to care about is his new woman.

Am I right to feel hurt that he no longer concerns himself with me now he is all better?
