Messy situation

My ex broke up with me about a month ago, we were together for almost a year and I was pretty blindsided by the breakup (didn’t recognize my needy, unattractive, and poor behavior). Thankfully the only begging and pleading I did was during the actual break up conversation. After she left I immediately initiated the no contact rule as I was fortunate enough to stumble across it soon after the break up, the only issue is that we work together. At work I make sure I greet her in a polite and upbeat manner, however when it comes to conversation I tend to keep it strictly work related except for some mild teasing when we’re in a group with fellow co-workers. I did however attend a celebration for her brother to wish him well and socialize with some of her family, she was at the event and did approach to make some small talk and joke. Is this considered breaking no contact?

The part where this situation gets messy is that we both have a trip that we’re going on with some of my Church friends and neither of us would be able to back out at this point. We leave for the trip in two weeks and I’d ideally like to send the elephant in the room text before the trip. Is that a bad idea?

I have been working on improving myself during the no contact period, going to the gym several times a week, keeping my grooming well maintained, going on dates with other girls, spending more time with friends, reading books to help advance my personnel growth and career. I definitely feel like I’m in a good place right now and I have the right mindset. Because I know that even though I love her and want her back, that there are plenty of other ladies for me to find.
