Dear Chloe:
I don’t know if it will be impossible, or very, very unlikely because I don’t have enough information about him or about the relationship you had with him, which you said was perfect for months. You are welcome to tell me all that you know about him (without identifying details such as names, ages, places etc.), his childhood, his current relationships with his parents and family members, and the relationship you had with him, as well as his current life circumstances, job etc., and I will reply further.
