Should I look for my ex grilfriend?

So for the first time in my life I fell in love real love. I dated this girl for 2 years and 3 months. and towards the end we started having problems and are arguing got really bad to the point where the was name calling middel fingers and crying. Even though things got that bad with her I swear i couldnt end the night that way and i always tried to reconcile before going to bed and ended it with an I love you. We broke up after a big fight we had and then I had to go back to sacramento for school and she stays in los angeles my home town. Before i left she told me she loved me and wanted to work it out so did I. So everything was on the right path up until valentines day. She told me she was going to Mexico and that she was going to call me back and she never did. It wasent till late march we finally spoke and she told me her family hated me and and asked if i was willing to live with that and i said yes. Then we didnt talk till i got back for spring break the last time i ever saw her. I told her i loved her and she told me she loved me too and had a beautiful moment and i swear the fire of the love i have for her than night lid up strong and she told me that i did the same thing to her. I then left again after spring break and we where fine for two weeks. We spoke on the phone everyday and then she stopped calling me for a weekend. She did it to me again. and she told me her brother didnt want to see me around and then i said we can work it out and she told me she had to go to her grandmothers house and I asked her if she was going to call me back and she never did. She ended up changing her number, blocked me from facebook, everything. I did see tho she posted a picture with her and some guy in may. So i FELT Like thats it she doesnt love me. Im on summer vacation right now and I want to look for her because she means everything to me and if its really over at least get a proper goodbye but I have mixed feelings because I dont know if I should. Last night i made it to her door and i couldn't knock. I cant believe im asking here but I am desperate Im a guy who just wants to find his peace and i dont want to feel like ill regret not going but i dont want her to feel like oh yea he still loves me u know? So what do I do guys advise please have u been through something similar? idk Help it will be appreciated :/
