We've been married for 5 years already.
Sometimes it feels like it's been much longer. Really, it sort of has. We dated for quite a while before tying the knot (we were quite young), so actually we've been together for about 9 years total.
Sometimes it feels like it hasn't been very long at all. My parents didn't even get to have their 5th wedding anniversary before my father was killed. We are so lucky to have each other during the short time that we're allowed in this life.
Enjoy your time with the people you love. Time sometimes runs out faster than you imagine it can.
