Thanks for the replies.
I most definitely do love the man I am with and I couldnt ask for a better person. We have had to endure incredible hardships financially, which is now sorted, the death of my father which was a very big blow for me and numerous other issues. Throughout all this he did not budge, he is steady as a rock. He is 100% committed and although no one can predict infidelity he does not show any other obvious danger signs. In my opinion we are soul mates and I am 30 and he is just a little younger so we have had our fair share of bad relationships. We work very hard at our relationship and do not let it rest on the fact that we really are great together.
Children are non negotiable.
So I am wondering if a marriage will be a worthy next step.
