Haven't been through it (yet), but can give you the perspective from an "older man".
If your desire for children with your man is there, do not enter into a bond without the same committment from him.
I am a 47 year old man, in love with a 23 year old woman. We have some hurdles, and haven't made any committment yet, but one of the biggies for her AND me, is to make a baby, or two.
I have four children, and empathize with your man's feelings, but if he can't commit to your wishes, you will be unfillfilled. If he truly loves you, he should be anxious to procreate with you. If he doesn't feel that way, you will be unfulfilled.
Hope this helps.
