Oh dear...

My sister and her boyfriend are having relationship problems. I feel slightly bad for them and wish they'd just work it out. He's over right now doing who knows what. But I will admit, they are moving fast. She told me they've already talked about babies and marriage and they've only been together for 2 months. Maybe 3. I am kind of jealous, not by how fast their moving. But how much they love each other. Will I ever find that?
