she blocked me ?

Okay I will admit I might've been just a little petty but I heard this girl was talking to my ex who was in jail for beating me at 7 months pregnant and he was telling her that he's not the father of my child and the results were I had many people coming at me with "is he really your child's farther" so I wanted to ask her if he really did say that I wasn't gunna cuss her out threatin her I just wanted to be for sure he actually said that so I won't feel bad for going to court for soul custody but anyways she added me then wen I guess realized who I was block me a minute later so I guess i should take that as a sign that my ex is denying my son witch is really sad ?  I know I will get some rude comments but I'm the type of person who needs these kind of answers to move on with my life otherwise I will feel like shit with unanswered questions
