<human>: Provide a brief overview of the text.

So I've been in a relationship with this girl for about 3 months now. We were friends from before the relationship began. We've spent about 11 days with each other in total over 3 seperate occasions. Otherwise we've been in contact daily through skype and texting etc. 

However, after my first visit at her place (3hrs away, living with her mom) things kind of got worse. We had some fights before and during my stay there. (She was in a bad mood from a lot of stuff going on in her life and took it out on me and other things. But we agreed to put all that behind us. 

It's been about 3 weeks since I got back from hers and I feel like she's less and less interested in talking to me. Until 2 weeks ago we talked with each other every single day since our relationship began and texted all day (60-100 a day).

About 1 week ago I brought it up and said that I felt like she's not really all that interested in talking with me and she said that there's a lot going on in her life but she would try to make an effort. 

It hasn't been any better and I can't shake the feeling of talking to some girl that's not really interested when I'm talking to her. This is my first real relationship so I don't really know how to handle this. Am I just overthinking this or should I be worried? 

Sorry for giving to little info and for my english, first time posting here and english is not my first language.
