So, I'm at the point of breaking up with a girl (or maybe past that point) and I don't know if I am making the right decision. We had been dating for around 4 months, and as far as I could tell everything was going fine. She had told me that she really liked me and had tried to introduce me to all of her friends. We saw each other at least once a week and would be in touch every few days. Then she went on holiday. The last time I saw her, a week before she left, things seemed fine between us. I texted her a couple of times after that and she seemed a little distant, took quite a long time to respond and was a little bit short, but didn't think that much of it at the time. Then she went on holiday, she told me she was going for 3 and a half weeks. I expected to hear from her at least after a week while she was there, didn't here anything for around 2 weeks. So I sent her a text asking how it was going, no response at all for another 2 and a half weeks. In her response it was like nothing had happened, just said holiday was great, how am I, etc. I was pretty angry and sent a response saying I got the impression she didn't want to see me, I don't want to be in a relationship with her because it's too casual. That was a week ago and received no response. I love her, but I think she can't be that bothered about me if she did that. I don't want to be with her if that is the case but I don't know exactly how she feels. Don't know whether to contact her again or just move on!
