So basically, me and my girlfriend have been going out for about a month now, but last week I went to visit some friends at their uni's as I haven't seen them in a while (this was planned way before I met the girl). We were texting each day and she was saying how she hated me not being back home, and we had planned to speak on the phone each night after she got home from work. She never rang, and didn't answer when I rang , and now I'm back she seems off with me and very blunt via text, and hasn't answered if I try to call, and has planned to see me twice but backed out last minute both days. Don't know if I've missed anything, but I can't see any reason why she would be acting like this.
Anyone got any ideas, or is it just me overthinking everything? Any help would be much appreciated
