To decide if someone deserves more loyalty, I would say it depends on the person or situatuation. If your significant other or family member is an untrusting person who lies a alot, then they obviously shouldn't be trusted. In my opinion, your significant other should already have your trust, and they should already have your loyalty because thats part of being in a relationship. The two of you should already give advice to one another on anything at all. If there is no trust or loyalty in a relationship, then perhaps it's not a "real or healthy" relationship.

Every time I have to decide if my significant other or family member should be trusted more, I think about the saying, " Blood is thicker than water." This saying always helps me decide who I should trust more. In the past, I have learned that trusting your family member is usually the better thing to do. Guys come and go, but you'll always have that family member by your side. I have also learned that taking advice from a family member is also the better thing to do because they are looking out for you, and usually want the best for you.
