Think about YOUR future spouse being is this situation with someone that you don’t know right this very minute. How far would you like them to go, knowing that this person has been set apart for you? That’s a good litmus test, I think.
I agree on the principle, but one surely wouldn’t enjoy seeing his or her future spouse even holding hands and saying sweet words to someone else in a romantic context, knowing it were his or her own future spouse.
Jesus in the room (because He actually is in the room…) is a good principle, too.
Some people will say that having an exclusive romantic relationship with someone is too far. It’s a very popular view among Catholics on these boards, but to keep my conscience clean I have to oppose it. Restricted Polygamy is worse than Serial Monogamy in my eyes.
You have to pray a lot and resort to your conscience. Preferably stick to people who believe in chastity. It’s going to be extremely hard if the other person doesn’t because it’s already hard with even both believing. Know your limits, know your emotions, talk to your Priest, ask his advice.
I would also suggest not seeking romantic relationships and not trying to be in a relationship and just waiting for such feelings to develop on their own. Also, being romantic with someone one knows one doesn’t ever want to marry is problematic.
I would strongly suggest having friends and hanging out with them on a friendly base until you actually fall in love with someone (or at least it seem so). This is also why I insist on romantic gesture or words being exclusive even if for this reason alone that out of N persons, N - 1 one already knows one isn’t going to marry. Not knowing who is going to stay and who is going to be out doesn’t change this. For someone being romantic with 5 people, there is 80% chance that he/she is doing romantic things with someone he/she isn’t going to marry. Plus, it’s polygamy. Restricted but still polygamy. I suggest having friends and strictly friends (doesn’t mean one can’t consider more than one for courting and later marriage) until one falls in love. Then I suggest waiting for some time to check if it’s a massive but short crush that quickly fades away or if it’s something closer to the real thing. If it looks like the real thing, I suggest going exclusive and discerning if the person is a good candidate for future spouse (if not, out). Jesus in the room principle is a good one at this stage and also remembering that both persons involved may well end up married to someone else.
I just don’t buy the stuff people say about holding hands and kissing with multiple people being harmless. How is someone who does that supposed to behave in marriage? How is someone who already cheats on his or her fiance(e) supposed to stay faithful in marriage? Cheating is wrong even if there has been no vow before God and it’s too far.
