She's dumping me....?

i was at a party the other night and i was drunk.. a guy came to me and disrespected me and said- take your phuckin car and go to a party for your own phuckin kind... so i said go phuck your mama.. the moment i said that she got angry and now she wants to break up with me because i said that... i love her.. is it a good reason to break up? i tried talking to her about it but she wants me to leave... even she talks using profanity sometimes
