If it's that easy for you to walk away after her not getting pregnant after only a few months, maybe you shouldn't have kids with her. Once you have kids, walking away shouldn't be an option. I'd think about storing your semen for future chances would be the prudent thing to do, but only if you don't find it so easy to split from her. Children are a lifelong responsibility, and marriages fall apart too easily nowadays, and the children are the ones damaged by the split. Oh well, lol....I tried? Sounds like a real match made in heaven to me.
