I really need some much needed advice

Samantha

So I recently found out that my first born son from another dad told me that his father just purchase a house. A house in which he is moving his Facebook gf that no one has met across the country to come and live with him and our son. My son has never met or talked to this person. I want him to be happy, but I don’t want my child to be living under a strangers roof. It took me 6 months to let my husband meet my son when we first started dating. So it’s crazy to me that this guy would buy a house for a stranger and move her across the country to live with both of them. Ugh!
