o i "was" talking from Nov- to beginning to feb to this guy and i really liked we would talk for hours on the phone and txt everyday unfortunately we lived two hours away and couldnt be anything .,but i stilled liked him and our communication didnt change so last friday we hung out and messed around ..a couple days later his homeboy told me he been talking to this girl for a month and a half and i checked his fb he didnt have anything indicating a relationship, I checked the girl profile and she has pics and love quotes, I honestly felt bad so i sent her a message " Hi,you dont know me but i know of you and this has been weighing on heart because i messed around with "him" friday I was visiting friends in the area and honestly if i knew yall were talking i wouldnt have done anything and that isnt my character i just wanted to apologize bc I see yall dating and didnt know anything about it" she read the message then the female blocked me ....did I do something wrong?!

Ya you got involved in her business. You are jealous which is why you did it and you know it.

So yes and no.
Ok so the guys friend could have been lieng.you never know if someone's telling the truth about that stuff anymore ... I think you shouldve confronted the guy and asked about it.
If the guy had actually done that you shouldve left it to him to tell her.how you told her was nice but could be seen as you trying to break them up..
