Even when you're down and blue, just remember that someone out there loves you, even if you don't know it and even if you haven't yet met them. There's someone out there waiting for you, remember that and keep faith. You'll get there.
Every relationship has problems but when those problems arise you have to realise that they don't mean your relationship is broken, it's just a little bent. Bent things can be fixed and like so your relationship can too. The first step however is realising that.
As soon as we fall in love and we realise we've met the one the rest of our lives can't come soon enough. It's not like you're in a rush to get to the finish line, you're in a rush to feel and experience everything and then do it all again.
