Sorry to hear this, I’d be broken and angry because he’s asking you to take responsibility for some difficult choice he has to do, that you have nothing to do with.
Not sure what culture this man comes from, but in some where arranged marriages are a reality, unfortunately it is quite common to play “boyfriend and girlfriend” until someone chosen by their family appears at the horizon. And follow suit.
To me it sounds all a bit fabricated…
As selfish as it may seem, I would challenge him on the grounds “this child is not my business, so don’t involve me. “
However it sounds like he has made his choice and is trying to simply find a way to leave with an excuse, his big plans being elsewhere.
if he cared for you and was a decent man he would take responsibility for this child, not necessarily for this woman. I don’t see why not.
several red flags also, like cheating, and did you ever meet his family? In some cultures family is king on the lives of others, if you haven’t been introduced you’re not part of his life yet.
awful..please respect yourself, he’s abusing your intelligence.
you can only maybe challenge him to confess the truth, and for me it is likely an arranged marriage coming up.
