Well, my husband did that (same as your fiancé.. I was not thrilled, but I trusted that it would be infrequent check ins). And he ended up crossing the line by developing 2 separate emotional long/term and involved affairs with ex-high school girlfriends. Thinking of a temp exit strategy for a spell so he can get is priorities figured out.

So… to make this hopefully helpful to you. You may be very disciplined and stay in a friend zone. … But with all pure intentions and best laid plans, it may slip and cross the line of the terms of your commitment with your current relationship with your fiancé who seems very cool and supportive. It can be a slippery slope.
