Do you think this is something to be concern about?

My boyfriend texts his sons mother on and off and a lot of times he is blocked just last month he was texting her all last money to see if she unblocked him and the reason why he said he texted her because something happened to the point his baby mother and her kids lost everything so he kept trying to reach out to her even though he got all the information from his brother who keeps in contact with my boyfriend sons mother but he said he still wanted to hear everything from her. I said why? She purposely have you blocked. And if you had all the information you needed and what to get your son you could have sent it to her and if you needed my help we could have came together to send them stuff. He still hasn’t sent nothing she finally contacted him about making more payments and he didn’t say a thing about his son.
