Good day brothers, please assess and advice my situation:

My ex-gf and I booked and paid a vacation trip last January for October along with her friend and her friend's bf. We broke up early August. I'm having second thoughts about going: on the upside I could practice TRP concepts and have fun in the process (recently just started swallowing the red pill after breakup), the downside is the ex being there, I'm not quite over her.
