Katherine,

It’s funny I stumbled upon this post… I deal with the same thing myself and it used to really bother me. I used to question our relationship but I actually haven’t thought about it in a while. I am not engaged yet, but am in a 2+ year relationship, and like you, I am always thinking (often over-thinking) my thoughts and actions, as well as other peoples thoughts and actions. While this introverted quality of his used to get to me (I used to spend hours researching introverts and how to deal with them) when I stopped worrying about it, everything worked itself out. I now realize how well we balance each other out. I’ve brought out the best in him, allowing him to be himself and sometimes let out his goofy side, and he has brought out a much more introverted side of me that I now love! I understand that our brains work differently and I often reach out to my family and friends when I want to deeply connect and talk about what’s on my over-analytic mind. It’s allowed me to form relationships outside of ours that I probably wouldn’t have made if I had a partner that talked about everything that I wanted to. I look forward to seeing what qualities our kids will carry on. Whether they’ll me like him, me or an equal split of both 🙂
In short, look at this as an opportunity. He was placed in your life for a reason and it’s something you can learn and grow from. In the end, whether you decide to marry him or not is up to you. I challenge you to look at your relationship in a new way and maybe form some new relationships to meet your emotional needs. Research introverts as well;)! You’ll learn alot about how wonderful they can be.

Best of luck! Everything will work out in the end, I promise!
