En passant is not forced up to your opponent to play it.
Chess.Com bug

Yeah, [deleted] gotta fix it. En passant is completely forced, you just have to play it if it is possible.

StumpyBlitzer is correct; en passant is not a forced move; it is an available move which one can choose to invoke. The legal right to play en passant is gone once it is not played on that immediate turn.
Wait a minute...you are trolling!
so I was playing chess rapid like I always do, this was the position and I was white. I played b4 forcing black to take the b4 pawn via En Passant so I can take their Rook
but instead they played Rook plays c5, I got so confused since everybody told me that En Passant is forced and left the game. I reasked everybody and they still said its forced, so i think this is a chess.com bug. Please fix this soon.
If you learnt it wrongly, you will remember it wrongly.
Who is "everybody"? You can ask the community here and I can assure you that it's not a compulsory-to-play move unlike checkers. Now it's no longer "everybody" since I have given my say.
Read FIDE Handbook, Article 3.7d. Based on the rules of chess by FIDE, the "everybody" you are talking about is incorrect.
EDIT: Saw your other threads as well. You are trolling as well.
