Break up

My girlfriend & I broke up with our other girlfriend last night. We moved states a few weeks ago & since then we barely talk to her. She also is seeing this new girl and barely has time for us. I should be more upset than I am. Idk. My girlfriend was crying about it last night and I just wasn’t. It was a 6 month relationship & I had kind of prepared myself to lose her when I knew that we were moving. Don’t really have the energy to be very sad I guess. I’ve been feeling sick since yesterday.
