Being shut out completely by a girl from work...

Hi,

Just after some advice about a problem I have. I've been dating this girl from work for about 2 months now. Things were going well and we both got on like a house on fire. Then about a week ago she messaged me saying she can't do this right now and that she has family/friend problems, plus her ex is getting involved and getting on her back. I can understand her issues...it's just she has totally blocked me out her life. She doesn't even say one word to me at work anymore and it's driving me mad thinking about! We used to get on so well but all of a sudden bam! Absolutely nothing from her... Is there anyone who can give me anything about what's going through her head at the moment?! I'm totally lost...
