"You can only really open yourself up so far to someone that you don't truly love - you keep something back when you know somewhere in your gut that this relationship is going to be forever"

This quote talks to the idea that when we remain in a relationship with someone we really enjoy, we want to open ourselves up entirely. We want to share our inmost thoughts and feelings, and we trust that the relationship will last permanently. On the other hand, when we are in a relationship with somebody we don't genuinely love, we tend to keep something back. We may not be as open and susceptible, and we might not have the exact same level of trust. This quote suggests that when we remain in a relationship with somebody we don't genuinely love, we may not be able to open ourselves up entirely, as we might not make sure if the relationship will last.
