How do i fix this.

I called my friend (woman) and phone opened accidentalöy for 5 min.

What happened was:
>she was taking many cannabis joints to person X
>Shes with the new bf
>I hear her tell him "dont tell anyone"
>it ends with him touching her between legs

I get enraged and wanna beat him up.

2 Days later:

>i see them
>she has extra money and she claims relative died and thats how she got it
>i blurb out who here has used cannabis in recent time, they both lift hand and laugh


Fast forward week

>i knew person x too
>i go to person x
>i tell person x that the new boyfriend went to the police and tried to tell them about you but they didnt accept the report

Fast forward 2 hours

>woman friend calls me
>wants to meet
>accuses me of spying her with gps or something, "how did you know I went to person X", denies all drug charges
>I admit i have no police friend and made a lucky guess based on your recent behaviour
>she finally says she has no rpmantic feelings for me and i loose my feelings for her too but regret what the fuck i just did

Next day:
Her former boyfriend associated with some gang calls me and says "never talk to anyone what you talked to her or someone beat you up
>I start to scream that im not afraid of your toy gang and ive made more crimes than you (actually likely maybe not) and ofcourse i wont talk but im not an asshole like you think
>he calms down


1 week ago:
> i tell woman friend im sorry and wanna say sorry to your new BF too, she doesnt respond, BF blocks me in facebook

They dont know i heard them through the phone. I wanna warn her to buy a new phone.

I wanna tell her im sorry. How do I do. Tell her the truth? Ive know her for years, she has known the new bf for only 60 days.

Ive also had many arguments with her and I think she will forgive me, shes just afraud to talk to me because she doesnt know what I know
