Didn't know that my interpretation is so accurate... Before that, i ever assume that he was angry of small matter is due to jealousy... but it is true that he is really jealous... ha ha... i was talking on the phone with his 'son' because i was on the way back home and was bored as just nice that he messaged me also nothing to do... so get his son to call me... in the night as i was talking to him, his son called... but without 20seconds, i hung his call and continued talking to my bf... then he kept asking who called... but i, of course, did not tell him that because i don't want him to think and worry too much... after he knew that it was his son that called, his tone changed tremendously... then he kept asking me to end my conversation with him and call his son saying that i am free to talk to him and everything... i kept explaining that it is impossible for me to talk to his son when my bf is free... so i kept asking him to tell me what had happened as i was suspecting that he might be jealous or have the wrong idea... then he wanted me to him my conversation between his son and i... so i told him everything except the part where his son knew that my bf and i are together... because i am not supposed to tell anyone...
