Wtf am i doin dis to myself i need sum advice and please no negativity

guys I just broke up wit my girlfriend and we been going out 4 almost a yr
I stiill love her very much but she moved on wit another guy
I tried bein friends with her and all that and it was going good till she told me that she was going to da movies...

wit him and wanted me to come along
and now she's asking me sum advice on how to convice him to have sex wit him like wtf
I know dis is my fault 4 allowin this 2myself but damn
what shoul I do

let her go man.she's moved on and you should too.you cant hang on to her forever because the end result will be you missing out on other opportunities and her living life.if you tried being her friend and she made you feel uncomfortable,express that to her.tell her you dont want to know about her relationship.tell her you dont want to third wheel on her date.ask her not to ask you about advice on her new boyfriend and their sex life.if not that,you can always completely let her go..hope I helped.
