It’s not that he is intolerant to lies. His friend of many years seems to be a compulsive liar. He is still adjusting towards him.

Like I said he never wanted to be with me in the long run. But after spending time with me, he may have realised that he could be happy with me. He did foresee difficulties with us being together even if I was his age. But after revealing my age he changed his stance altogether. Btw his sister who recently got married is elder to her husband by few years.

He seems to have analysed that just him and me can be happy  but his family and friends won’t be happy that we are together.
