So i dated a guy for 8 months. while we were together sometimes i had money issues and he was trying to give me money. i never wanted to take it but cuz he said just pay him back when i have it. then we been broke for 18 months and he knows im getting marry he texted me to ask for money back. after broke up we still sometimes talking like friends and i did asked him to pay back couple times but he never want to get it. so should i pay him or not?
