So I've been going out with this girl for a bit over 2 months. I met her at uni, and I found out that she works like 20-25 hour weeks while at Uni, and that she pays upfront for Uni. Fair enough, so she wants to have some money to pay for all the shit she wants plus Uni, lol. Up until exam week we always seemed to see each other usually on Thursday/Friday/Saturday because other days she was at Uni or at work (I was also at Uni/work). This was repeated pretty much every week until 2 weeks ago, when exams start. The weekend before study week everything was going good, she rang me on the Friday and we talked for 20 mins, even though I was at a party where I knew no one and I was essentially just a random talking on the phone ), then I took her to the Autosalon(car show) and went back to her place for a few drinks. She got sick from drinking too much but meh. The next morning before she went to work she woke me up by jumping on the bed next to me and we just laid there together hugging and crap as it was 5am and I couldn't be stuffed doing anything other than that (no we didn't sleep together ). She kissed me and then went to work after that. She got a crappy exam time table (3 exams in 4 days then one a week after the last of those 3), and mine was pretty spread out. We planned to go out on the Thursday night, but she postponed it till the next Wednesday (because she had the exams on Saturday, Monday, Tuesday). When I saw her at the exam on Monday (we had it together), she told me she had a bad exam on Saturday and that's why my txt that asked her how she went was never replied to. Then I asked her if we were still going to the movies on the Wednesday night and she said "I don't know, I changed my availability at work". So I rang her on Wednesday and she was at work in the morning, then I sent her a txt in the afternoon before I went to work because her home phone was engaged. After my shift was over at work (5 hours later) she finally txt'd me back with "Hey Dale, I'll be busy for the next few weeks. Maybe when things quiet down a bit". Then we exchanged a few more txt's and I find that she has more hours at work and needs the money. Fast forward to yesterday, seeing I hadn't talked to her for a week, I txt'd her asking her if she would be home after her last exam because I wanted to ring her, and I haven't got a message back. I don't know whether I should call her on her home phone tonight because she hasn't messaged me back. Shits me off. Could she really be that busy that she can't return a text message? It's already been a week since she said she was too busy, and I'm getting all fucking insecure and shit. What do you reckon I should do? Call her tonight or wait a few weeks? EDIT: She's been going on about changing her availabilities for aaages and she keeps asking me whether I was changing mine or not. So I don't think she's changed anything suddenly because she decided she didn't like me over the exam week or something.
