What is entailed for someone who tried to joke and flirt with a foreign girl during the daytime in Ramadan, then broke his fast, thinking that his action had invalidated his fasting?

What occurred is a result of residing in lands of disbelief and co-educational studies. Intentionally breaking the fast during the day in Ramadan is a grave error requiring seeking forgiveness and continuing the fast. Satan hinders good deeds under the pretext of unworthiness. The emission of madhy (pre-seminal fluid) does not invalidate the fast according to the soundest opinion among scholars. It is impure, invalidates ablution, and it suffices to sprinkle water on what it soiled; a full bath is not required. The day on which the fast was broken must be made up, along with repentance. The severe expiation (kaffarah mughalladhah) is not obligatory. If the make-up fast is delayed until another Ramadan, a delay expiation becomes obligatory, which is feeding a poor person.
