My girlfriend wants a break.. is it really over?

we have been going out for 2 months. i really like this girl, and it seemed like she really liked me. we fight more than we should for 2 months. but thats because at some point i caught her flirting through texts which caused me to be so insecure. we fought a lot about that. we have a lot of good times but always seemed to end in an argument.. then we would make up. but tongiht we had a really fun time, everything was perfect, and she looked through my texts at dinner and saw that i was going to a party after we hung out.. she has a curfew at 10 and is 18 yrs old .. im 21.. so i was going to go.. and she said i knew you were the partier type.. and we got in this argument where things were being brought up.. like i saw her flirting with a guy through texts when i was out at the bars.. but hes nothing to worry about becasue hes ugly and we work with him.. then she got upset.. and said its over.. then said.. maybe i just need a break.. is it really over?? she told me i never invite her to things.. but i really do.. as we were talking we both teared up and it seemed hard to do for both of us.. is it really over???
