Hmm, yes I'm not sure why she would want to maintain a 'friendship' with you (which reads like borderline dating) whilst seeing a new guy..
For me, it's less a case of thinking about what's the status there - how does she feel about me, him etc... And more about living your own life as you want to. How do you feel about being in contact within this context and what's okay for you, given what she has told you.
I think for now she has chosen not to 'tip over the line' into dating with you and has mentioned someone else in the mix - so that's how things are for now and you may want to pull back a little given that.
What I do see is that she appears to be the only person you socialise with and she just told you she is seeing someone else. So you may want to seek to broaden your options for getting out and about and doing things with others too...
JMHO of course Tad and I hope this helps :)x
