Do I tell my ex that I am pregnant?
So this is an extremely long story but for context here is my first post: https://www.reddit.com/user/throwawayuni33/comments/1rruxpc/i_ran_away_from_my_boyfriends_proposal/?utm_source=share&utm_medium=web3x&utm_name=web3xcss&utm_term=1&utm_content=share_button
For shorter context, my boyfriend(22M) proposed to me(20F) in a park, I was uncomfortable and ran away, and it became this whole big thing between me and him. He was very upset and I handled it poorly, and it ended it with us splitting. We both behaved immaturely in my opinion and had to end things due to cultural differences and expectations.
I found out I was pregnant a few weeks ago, and I think the baby was conceived a little over two months ago even though I took Plan B. I already am having a friend come with me to the GP to get an abortion, but I don't if I would be the asshole never telling him. Does he have the right to know?
I also know we should just go our separate ways for both of our sakes and I am worried if I reach out again, we might get together again. I am trying to be as mature as possible so please let me know what the right answer is. Thank you.
