What does this mean?

ok well me and my girlfirend have been going out for about 2 years and the week before last I was out of town so I didn’t get to see her that week but we still got to talk over the phone then the last day of my trip she went out of town and because of her location we couldn’t talk for a week so we haven’t seen her for 2 weeks then Finaly she comes home and I text her and ask her to text me after she gets back just sothat I will know that she is safe well she never texted so I figured she was tired so I went on to bed and I had yet to recieve a message back so then the day after I saw her and she seemed…not excited al all to see me and today we haven’t talked at all and I asked her if she would tell me what is going on between us but I still have yet to recieve and message
