You're a Stranger

This morning my son crawled into my bed and I called my daughter to join us stating I wanted all my children in bed with me. My son then stated, out of the blue that I am not his biological dad and that I am a stranger. Now I know he as a 9 year old likes saying things at times to get a rise out of me. I stated that he is right that biologically I am not their dad but asked why he responded like this now. He stated it was my statement about "all my children".

It's amazing how a simple statement, despite it's truth, and how long I have been dealing with this, still hurts.

He stated something that he has been having conversations with his mom. I didn't quite get what he said was in those conversations and I will be asking her.

I asked him after we got out of bed what prompted this again and again he stated it was my "all my children" statement. I told him I loved him and although I love him very much the stranger statement still stung. He replied how do I know you're not lying. Here I know he is baiting me but still what makes kids say things you never know.

Definitely want to speak to their mom.

Update:

One thing I should make clear is that the kid's mom and I have always been in agreement in how we discuss the donor and my being the kid's dad. She and I actually spoke this morning and I know she has never nor woud she ever use words like stranger when discussing my relationship to the children.

I think my son, in his choice of the word stranger, was simply looking for a word to mean "not biological". He did ask me about the donor and I did not know what to say as we only know what we know from the profiles. We are all good now. Had a good trip to camp and drop off.
