Overthinking?

I neec help. Im very depress and over thinking. I dont know what to do. I haveba.girlfriend and been dating for a month, but i havent had no communication with her for like 2 weeks...because she has no more phone. I have a new girfriend now and i told her once she gets online, im going to break up with her cuz of no talking. What should i do?

Why do you have a new gf if you already had one.? I think that you should have waited to break up with her before you got with someone else.. Personally
