In my 20 years in this exquisite world we live in, I have watched a number of romance flicks which usually ends happily and/or tragically (like Romeo and Juliet, both the old and new version). I am writing this because I have learned one thing in watching those flicks.
No matter how people judge you (and your partner), it is still up to you if you will ignore those people around and just continue being happy with your life together. Besides, forever is a choice you make.
Stressing that forever is a choice you make, you should know that if you want to spend the rest of your lives together, you (both of you) should continue loving each other and do not let problems destroy you. Problems are always there and will make a way to destroy you yet you should solve it not just let it devastate everything you have built.
Yet, even if it is the bravest thing to do, it may also be the hard since pride is difficult to lower down.
