I think most would agree that being aesthetically pleasing, having a trust fund, and taking good care of you are not enough sustenance for a healthy long term marriage.
Nor are any other reasons that belong in the "what can she do for me" category.
She can make you spontaneously laugh from your belly? Here and there, her thoughts prompt you to consider a new perspective? Specifically, do both of you have about the same tolerance level for other people's beliefs?
You admire the way she treats others, especially in instances when she doesn't realize that you are aware of what she is doing? If not, think carefully about how this might affect the way that you feel about raising your children together.
I wouldn't want to rely on such feelings to keep my life partnership healthy and intact.
I encouraged my children to not date when all their friends were dating at 13yo. It wasn't until that time that I was able to find the person I wanted to spend the rest of my life with.
I told them dating is a prelude to marriage and that this was not the time in their life to pursue this. Figure out who you are - what you like/don't like. My own personal experience was that I spent a lot of time trying to impress those I liked and becoming something that I wasn't. I also told my kids you need someone to go the distance with you.
, which I think is a symptom of being intoxicated with lust; healthy and respectful lust is great, of course, but probably not the best primary source of fuel to maintain a healthy relationship over the long term.
How do you know if you genuinely like and admire him?
