the most IMPORTANT of all is to bring God into your relationship.
A question arose in my mind. For a romantic relationship without wedlock how can God be kept in? I mean I don't know if there is any religion that accepts the relation out of wed-lock and thus God, according to no religion, be with the sinful act.
Prayers are important to make us closer to our God and find the light of guidance. Nevertheless, I believe, prayers are not enough. We need to counter our problems practically along with seeking the strength from God.
Surrounding ourselves with good people is beneficial in general. So it can be good for saving a relationship too.
Yeah prayers are good, going to mass together too. Basically always putting God first before anyone (or anything) else, even your partner. Perfect example of that on media can be seen in Jesus Revolution. 😉
Indeed it's also good to hang with the right crowd. Am not saying just pray and don't do anything else. It's just that most people don't do much of what I shared so it has to be said.
