Iam russian so sorry for my english...try to understand if something isn't written right...
Iam 21 years old she is 24, we have been dating 2 months, we met and clicked, she was massive shit testing me because i look good and she knew that i was fucking girls regulary...anyway i went with her into relationship it was hard at first but then i knew her better and she is really a good girl, aweomse, adorble, and hot( we ended up having sex like 7 times in 24 Iam the first one she was able to cum because the dudes who were with her were TOTAL AFC)...but she got a problem she is insecure as fuck! i tell you WTF happend friday night, some dude got bday and i and my gf went to the party, so it was all perfect and nice, alot of smiling and laughing, then like in 3:40 mt girl and our mutual friend, we were sitting in bus station because our friends went to a pub, to see if it was closed so we wouldn't waste money for nothing...so THIS SHIT HAPPENS!!! some girl got out from a taxi, and my friend said "oh wow she is sexy' and i told him "she is my friends gf arnt you ashamed?" in a funny way then again he said "she is sexy as fuck!" in some point in my GF head she mixed it on me! what i mean? "you just told that she is preety and you arn't ashamed to admit it" i was like wtf( massive shit test) i was like "wtf are you talking about?" well the problem is i proved her wrong i explained really good what happend, then she is like "You said you saw her on a bus!" well at this point i couln't handle this shit anymore! this fucking 2 month of shit testing me!!! every time i proved her iam the man! in real life and in the bed, so.... i went berseked on her "ARE YOU FUCKING INSANE? what is wrong with you?! fuck this! iam going home have fun together and go to that friends of our house" after couple of minutes she says "forget about you knowing me anymore.." so i didn't talk to her 1 day to chill and then to talk to her (Iam very optimistic person but i just snapped...) so i told her that i understand what happend and it was alcohol involved (wasnt drunk) and you mad at me and the way i left you in your face it's becasue if i stayed i would say words i don't want to...so i left text me when you want to meet and talk about it..
she said "i got nothing to talk about with you, good you rememberd talking to me, so keep doing wtf you are doing all day bye"
long story short, after she said to me this shit... I went to my friends house and fucked her...so my back is all scratched and shit... but now i keep wondering? if my gf said it's over? or just needed some space? maybe i made a mistake that i fucked after 1 day of depression and tear another girl? should i ask her is it over? wtf i do guys help me....SHOULD I say sorry? like sorry I got mad and stuff like that? if i need to say sorry how should i tell it to her? say it?
