There can be a lot of pressure to have the perfect life together, but life can be hard work! Don't assume that the reason you're struggling is because the relationship itself is the problem.
When things aren't going quite right between you, try to remember that there could be other reasons.
Maybe one or both of you is facing up to some big challenges?
It could also be that there are some things you need to talk about before your relationship can move to a new, stronger level.
