CONGRATULATIONS on your engagement!! I wish you two many happy years together!! I will assume he's active duty - it's a long tour - as they usually only do 12 months at a time, not 24.
In regards to your biological father the military will NOT pay for a paternity test at this stage. If you were an infant and there was a question as to your paternity and child support, then yes, they would. But you are legally an adult and they will not get involved.
I'm confused as to why this is important to you. I will make an assumption that you've not had contact with him in the past. My question to you would be this - why is this so important to you? If you have not had contact with him - what makes it so important now? What do you want from him? Acceptance? I am sorry if this hurts - but there are times when bluntness is required - if he has not had contact with you up until now - you won't get anything from him now - this will be HIS loss, not yours. DO NOT take this burden on.
Think about WHY you are doing this. Why is this so important to you? Answer these questions and it will help you come to your own closure.
Ask your mom if there is ANY doubt on her part on who your biological father is. It may sound offensive - explain to her what he said. If this is so important to you. Realize you may be opening a Pandora's Box and you must be prepared for the realization that you may learn things you didn't want to know.
If you can't let this go. Ask him to do a paternity test. I think they cost about $250 - I don't know for sure, sorry. But again, I ask -
why do you need to do this?
What do you want to prove?
What do you think you will gain from this?
Think this out. If this man who is your biological father hasn't had contact with you in the past - do you think a paternity test will change this?
Why do you want to prove that he is your biological father? I will state again - if he hasn't been actively involved in your life up to this point - a paternity test MOST LIKELY will NOT change this. He lack of involvement in your life is HIS LOSS.
I apologize for the length of this response. Please think about why you FEEL the NEED to do this, what you want to prove and what you believe you will gain in getting the definitive answer that he is your biological father.
Best regards,
Cheryl
