Girlfriend went crazy after a simple fight ad now blocked me?

We were dating for two years becoming serious for the past few months really good together I was away due to work and when I came back she said she will come and meet at my place as her relative is there then she changed the plan few times and said let's go out I didn't want to but
I went to her place to surprise her and but it didn't go well and she was acting weird and I made a massive mistake and cause argument saying that I'm tired and won't come out and she got angry then I said fine if you insist I will and and she got angry and told me let's meet tomorrow and talk later and I tried to talk to her to go out but she didn't let go and I left
She went out when I left
Now after she blocked me everywhere tried calling her but didn't go though
Pleas e help me
I thought send he flowers with a note and I did but no response
It's almost One week gone and im going mad
This is very childish behaviour without even any conversation to cut all
I don't understand we have a trip plannned in the next week and I don't know what I should do anymore ticket hotel everything booked
tried sending next through my friends phone she read it and blocked him as well
what's going on
Should I approach her or... I'm going crazy and I really do love this girl
