should I leave him for being pro life?

A man doesn't have a right to an opinion that babies shouldn't die? Interesting.

This really isn't a wedding problem. If you're this far apart, you should call it a day.

If your periods are this painful, you should consult your OB/GYN for some help. If you're suffering like this, asking him to do something about the pain when you won't do anything yourself is being kind of a drama queen.

The two of you are very poorly matched. If he wants a baby, he's not going to stop nagging, there will just be a greater or lesser amount of nagging. You are far apart in age. You're in different places in your lives. You want different things.

I don't understand why you're with him, unless he provides you with financial security. And that's not a very liberated position for a woman to take, in this day and age.
