what is something you got wrong recently — and what did it quietly teach you?

I had a boyfriend in my first year of college I don't usually go after relationship but I don't know why I did that at first he was soo good that I was thinking to marry him but after sometime I have seen that he was not like before like he started insulting me in public in front of my friends like how fatt I am and how I don't know to read Hindi properly I was quite I let him insult me but in person he was not like that and every time I met him alone every time he tries to sexual stuff and I hate this kind of things I have told him before he even said many bad words like someone else would have done something to u but u are lucky it's me I feel so disgusting when I hear that I still try to be understanding gf but it was all in vain so I have broken up with him and told he that he was wrong by insulting me and saying bad stuff now I feel so good and nice not have a relationship sometimes feel sad and lonely but believe me don't Chase someone wrong in search of your right one IT takes time but it will not break you peace by peace
