Don’t feel like you need to do what society expects of you in order to have a lasting, healthy marriage or relationship. You have absolutely nothing to prove. We are lucky to live in a country in which you can do whatever you want. If your gut tells you its right, then listen to it.
I suppose I just want you to know that if you love someone and want to spend the rest of your life with them…you need to tell them. Even if marriage isn’t for you. Tell them how you feel and that they’re it for you.
