I often hear about engaged heterosexual couples who want to live together but not engage in marital relations until their wedding day, as their intentions are trying to be in the spirit of Church teaching but also want to save money by sharing expenses, etc.
I do not know of one orthodox priest, including Fr. Serpa here on CA, who advises such a thing. There is the risk of temptation as stated before, and I do appreciate the other poster who said it is possible as per their experience. There are other things to consider too in this example. We aren’t to lead each other into scandal, and the appearence of co-habitation between unmarried heteros can lead others to think that intentions aren’t where they should be. While we shouldn’t always be concerned with what others think, a cohabitating hetero couple could surely lose their witness, leading others to lose theirs as well.
I’m not so sure this example isn’t pertinent to a situation of former homosexuals living together chastely.
I don’t want to condemn anyone to lonliness by stating these things, and certainly there is no judgement of hearts here

, but I am stating truth so that we all can be free. My heart to all those who struggle, but condoning something that isn’t true or life-affirming for the sake of being nice is false compassion IMHO.
