I am a single mom again (as of a week ago) of a 5- (almost 6-) year-old, who is in kindergarten.
My son's biological dad and I were together 5 years but we lived apart by the time I got pregnant. He pushed us out of his life pretty much as I got pregnant. He wanted me to abort him, but I refused.
Though he wanted me to have an abortion, he was present for his birth and visited 2 times, celebrated his 1st birthday together, then he simply stopped seeing him. No support, no legal stuff done; I left the area to live with my mom. Before I left, I was starting a relationship with a man that I knew for 4 years. We did end up having a very loving relationship, a long distance one, and because my son was so young at the time, he eventually became "dad". We were together almost 4 years.
He wanted him to be his son. He said through the years that we were together that he loved him as his son. (We had been together a total of almost 4 years; it ended a week ago.)
I did not take lightly him being called dad. He moved in with us (multigenerational household). Things were good, but he was away a lot with his work, yet I feel we did well together and as a whole family.
Last week, he said he hated living in "the city" and had to leave. I was blindsided. Now my son has basically lost two daddies.
My son is smart and articulate. I don't need to talk to him about his bio dad since he never knew him, but how am I to approach him about the daddy he knows now that he's gone? Right now, I'm pretty sure he thinks he's just at work. He talks about him but hasn't asked where he is yet. He lives with me, my mom, his adult sister, including our next door neighbor, and numerous family members that visit. So he has lots of love around. No abuse. Normal, for us, family life.
What to do? How to tell him?
