Mixed signals from a girl, should I walk away?
Me and this girl were on and off dating for about 10 months last year. We were extremely close. We would see each other at least 3 times a week, even in the periods when we weren't hooking up or dating. We were pretty much best friends. In December she went back to her ex of 4 years and we didn't speak for 4 months. I saw her 4 months later and she said they broke up and we started seeing each other again for the past 3 months. Now this last month she told me we're just friends again, and I said fine and started going no contact. After that day I seen her once a week and every time we have kissed and been super close, yet after the time spent she goes distant and I don't hear from her for like a week.
So last Friday we hung out and everything was great. On the Monday I tried to call her, she ignored my call, didn't call back. Tuesday I tried to call her again twice, no answer no call back. Then it happened. My grandfather passed away on Wednesday morning and I am living in another country so I was very sad and lonely. I texted her asking if she's OK cause she didn't return my calls and I told her the sad news and I said I could really use someone to talk to. Well she replied immediately saying she's sorry for my loss etc and said she will call me later. Didn't hear from her all day, so I called her in the evening. No reply but she called back straight away and was very offish on the phone, like she had to speak to me. Then after about 2 minutes on the phone, she said she has another call, she'll call me back. No call back. Texted her an hour later saying if you're not busy after work do you want to come hang out, I could use a laugh and just relax with you. No reply.
Everyone I know has gone out their way to message me and call me to see how I am doing, yet the girl I care for the most acted like she couldn't give 2 s**** and I haven't even heard a word from her. We supposed to be close friends even if we are not dating. So I'm really hurt and disappointed that she would act this way. All I needed was to talk to her and for her to show a bit of compassion. Is this the right time for me to just walk away, or do I call her out on this?
