I was in a relationship with someone in 10 th class he was very uncertain due to his parents after that one day he broke up with me said his parents got to know and denied talking to any girl including one of my frnds and me they are very strict and they will supervision his mobile usage but after that he replied 3 times to my message I had asked him to send me a letter for assurance in future and he agreed but afterwards he didn't replied or see my message further and didn't send me the letter after 4 days he replied to one of my female frnd talked nicely then also 5 times he replied to that female frnd normally but still he said he had problems in home but replied despite his denial of parents so I doubted then after 15 day I messaged him but he blocked me I think his mother saw my message and due to that I am depressed from 3 years I had messaged him that I am depressed I am overthinking a lot about his parents whether they are ok or not if something happened to them is it my fault
