One Sided?

I met Julia recently when I was with someone else. They cheated on me and we broke up. Me and Julia have been getting to know each other and I really like her. I also trust her I hope. We were due to meet up one weekend, but the weekend before I invited her to stay. She said yes and we spent the weekend together and it was lovely. She then returned the following weekend as planned and that was fun too. She has invited me to visit her, and I would love to, but I am a student and don't have a great deal of money at present. She offered to pay for me but I said no, as I hardly know her, and as such we are not together, just still getting to know each other. She thinks I am being unthoughtful, as I told her one night that I wanted to see her and would travel the next day. I didn't take the journey and she was upset by this. I do want to see her, but appreciate the distance between us, and I am still hurt by what happened in my life recently, which I don't talk to Julia about, as I feel she won't want to hear about my ex partner.
