I think people are being a bit unfair to JessieJ. If she is 32 then baby wise she needs to get going.
I don't think it is at all unreasonable to want that level of commitment. Whereas the institution of marriage does not automatically guarantee eternal bliss, that doesn't undermine the concept of marriage which is two people saying to eachother 'I find you so important to me that I am prepared to enter into an exclusive commitment'. Whatever the progressives say, women AND men still want to get married.
But Jessie the red flags that people are bringing up are valid. Why can't you talk about this? What is with the silently wishing and hoping - where are YOU in all of this? Have you brought up the idea of children together, and what is his reaction? (if you definitely want to have children and his reaction is not good, DON"T deny it. You will be making a choice between taking the risk of finding someone who does want to have children with you, or choosing him and childlessness).
And the fact that he is into you and can't get enough of you is meaningless. That is sex, not love. So maybe you need to work out what love is, and whether you have it.
This is what I have found (we were also hugely 'into' eachother. Means nothing when the conflicts start and you have no communication):
A relationship is the space between two different, separate individuals who ARE going to clash. Because they are different. In this space you should be safe enough to say what you really think, want, feel (in a respectful way) and the other person care enough about you to hear you. Then they put what they want, think feel into that space, you hear them, and you negotiate for a mutually beneficial outcome. It is a rising spiral of growth and connection, each wanting the best for the other and each giving a bit to get it.
I have been married for over 20 years and I don't have it. Take great care JessieJ for what you wish for. Spend time thinking about what you want, and then when you are sure, speak clearly and non-manipulatively. He has the right to disagree with you if that is not what he wants, and you must accept his needs too. (walk away if they don't agree with yours. 20 years of frustration and hurt is behind that advice!)
