Sneaky link is pregnant 🤰🏻

So I’ve known this guy for about a year. We barely started TALKING 3 weeks ago. I’ve had the BEST dates with him, our time is always spontaneous and sweet. He ghosted me a few days ago. He then recently called me crying. The reason he had ghosted me is because his old sneaky link is 6 weeks pregnant. I don’t know what to do here. He said he’s going to get a DNA test done; if the child is his he’s going to take responsibility. THE whole situation was a turn off to me. I feel a little lost and indecisive with a sprinkle of anxiety
