Been in a LTR for a little over a year, Getting tired of her shit tests/attitude etc and have been focusing on myself more while giving her less of my time & attention. Also started a new job recently, Met a cute girl there and we hit it off right off the bat so I decided to go out of my comfort zone and ask her to lunch. She doesn't know i'm in a relationship and I told my gf i will be going out to lunch with some co-workers. We were supposed to go today at 4, But I was invited down the shore to bar hop. I texted her and let her know i'd probably have to cancel and she said good idea because her friends dad died and she's upset. Starting to get cold feet tbh.. This could end in many different bad ways considering my relationship and that I work with this girl. How should I go about this?
