So I split up with my girlfriend, she didn't feel the same way anymore which hurt but we both agreed it wouldn't be worth trying to fix if she wasn't 100% in it. Anyway we work together as well. We share the same social circle (mostly mine) at work but when I went no contact she had no one and looked miserable. They say if you love someone you do what's best for them even if that doesn't include you. At this point there's no chance I'd get back together, it's too damaged however I have no Ill will towards her. Just wonder what advice you'd give, to protect myself from hurt when she moves on but also ensure she isn't isolated at work and I can support without being jealous/weird.
