<human>: I (28F) know it probably sounds paranoid but I've been thinking about it a lot lately.

A friend (35M) who once told me that he always liked the idea of getting married and have his own little family. Lately he has been pursuing me. My immediate thoughts were, does he actually like me? Or does he go for ANY one that might want the same thing? How do I know that he likes me for who I am or he's just desperate for a relationship? 

We've known each other for a few months now and he has always been really great to me, but again I thought, he could be nice to anyone that gave him the chance?

Is it weird? What's wrong with me? Does anyone else think this way? Married people, how do you know your partner wanted you, only you?

Summarize the given text in a few sentences.
<bot>: A guy who always wants to settle down is pursing me, how do I know if he just wants ANY relationship or am I something special to him?
