in need of some prayers or positive vibes!!

my daughters father who hasn't been involved in her life the past 2 1/2 months by his choice has been trying to serve me a DNA test. I'm not looking for any parent shaming, just some positive vibes. I'm glad he wants to be in her life but this is so so hard on me. I don't understand how someone who has done nothing for his child just expects her to be laid in his lap. I hate this for everyone involved. I'm so so hurt today.
