I'm relocating to the UK with my sister and feeling uncertain about my relationship with my boyfriend.

I’ve been living with my boyfriend for the past five years in a rented apartment in Canada. Recently, my sister and I obtained our Irish citizenships, and we're planning to move to London, UK at the beginning of June. We’re considering working in live-in pub jobs initially to make the transition smoother before searching for positions in our respective fields. However, since I would be staying in a small room at the pub, my boyfriend wouldn’t be able to join me there. I’m eager to take this chance to meet new people and travel around Europe during May with my sister, who hasn’t visited in over seven years. Ideally, I’d like to do this trip without my boyfriend, as we already had a European getaway last year. However, I'm uncertain about how to approach this topic with him and my family, especially since they are not in favor of me moving away.
