<human>: We've been together for a year and a half, lived together for about six months. 

I feel like I've known for awhile -- maybe even since the beginning -- that I would eventually break up with him. We just have fundamental differences, the biggest for me being I am super affectionate, he's not affectionate at all, and I want a way more active sex life than he does. Also, we just want different types of lives -- he wants a more stable, "normal" life, I want more adventure.

It really sucks because we have a great relationship. Nothing "bad" has ever happened, he treats me amazingly, he's a great, great, GREAT person. But I just felt like I had to do it. We're not getting younger and I don't want to waste either of our time. My friend offered that I could stay in her spare bedroom, and I just decided it was the right time to do it.

He's completely confused and heartbroken (I'm heartbroken too). I woke up this morning doubting my decision, and I was just hoping someone out there had gone through a similar situation and could give me some words of encouragement or advice. Thank you!

Can you condense the text into three sentences or less?
<bot>: I broke up with my awesome bf because I knew I eventually would anyway. Feeling crappy about it and need encouragement.
