If you don’t pay the expiation intentionally, you won’t be forgiven.
Actually, before I broke my fast, i have the thoughts that i am worshipping my desires and wife if i broke my fast and have intercourse with her yet i still went ahead and do it. If i repented but did not even try to fast back 14 months of 7 days that i purposely skipped and die this way. Will my sins be forgiven? If not, is it shirk or sins of breaking fast?
