Can somebody help me please, I have a dilemma?

I say, go with Tom. See, you and Gregg aren't in "love", you're both just really attracted to each other, probably because he's a bad-*** who has a soft-side. But, Tom and you have a long history together and you both are more similar to each other than you and Gregg. I say go with the one who you are most similar too, because contrary to popular belief "opposites attract, but they don't last."
