Dear Dáithí: My perfect girlfriend is horrible to me behind closed doors

We’ve built a life together, but I don’t feel I can relax or be myself around her, like I need to improve on everything. I keep hoping things will get better, but they don’t. How do you know when it’s time to stop trying — and start walking away?

Dáithí Ó Sé: "I’m going to be blunt — you need to run for the hills and here is why...'

I’m 29 and have been in a relationship for almost four years. 

My girlfriend is funny, vivacious, and everyone loves her; she is drop-dead gorgeous, really outgoing, and has a glamorous job.
