<human>: I'm planning on breaking up with my 30f girlfriend tonight and am a 34m. We've been together about 6months, maybe a bit longer.

The reason for breaking up is that I'm just not that into the relationship emotionally, and I feel as though I should be by now. I have a history of waiting until a relationship gets bad enough to end (which the girl typically does) so that I have a "reason."

The reason I'm conflicted is because she is a great girl and has been good to me, but my past relationships (though they have ended, some better than others) were way more emotionally intense.

When we first started dating, I noticed the lack of spark but thought it might be healthy for me to have a relationship that didn't jump out of the gates at lightning speed. Since then, the emotional connection hasn't really grown on my part but I believe it has on hers. I have also kissed someone else while dating her, which is something I never have and would never do in the past.

I think I know the answer here, but am looking for outside perspective. Should I do it (thinking of doing it tonight) and what's the best way to go about it, if I should indeed do it? I know it seems ridiculous to be asking about this online at my age, but I've always been the dumpee after waiting out past bad relationships out of fear of hurting them. I don't want to make the same mistake again.

Can you condense the text into three sentences or less?
