To be perfectly honest, I don't know why the fuck you're even writing to me. Sounds like you've already made up your mind and are just looking for confirmation. Well....
It's a tough call. Rebound is a tricky thing with one person, but now you're BOTH on the rebound. If ya ask me, you're both hurting and seeking out a "comfort zone" with each other. I got back together with my first love once or twice because of this, so I know how it feels. Trouble is, my first love and I are two entirely different people who, frankly, were never a "match" to begin with, no matter how much we loved each other. The love was real, but the compatibility wasn't.
What you need to do right now is set aside your emotions. Sto being lead around by your heart strings! Don't ask yourself if the two of you love each other, ask yourself if the two of you are RIGHT for each other. Love is an important element to a successful relationship, but contrary to the fairy tale bullshit, it is NOT the only element needed! John Lennon said "All ya need is love." That man was full of horseshit. Love is important, but if it's ALL you've got, you're doomed.
Think about why your relationship with this guy ended in the first place. Relationships that end usually have a reason for doing so. Now, I'm not saying you should just drop the guy. If he makes you happy and it's nice in your "comfort zone" then fine, stick to that for a little while. But DO NOT delude yourself into thinking that it'll be some perfectly little happliy-ever-after thing. It could turn out that way, but it most likely will not. It'll be a pleasant surprise for you if it turns out well, but don't expect that to be in your future with this guy.
The honest truth is that both of you need a safe place for your heart to heal and you found that safe place with each other. Once the healing is done, what's left? Love? Pfft! Spare me that crap! Leave that shit to Shrek and Fiona, it doesn't happen that way in real life, most of the time.
Go ahead and enjoy your little safe zone. In fact, enjoy your new relationship with this guy, cuz I already know you won't fucking listen to me. You'll fire up the relationship again anyway and find out that I'm right the hard way, just like everybody else. For what it's worth, I hope I'm wrong and it works out for you, but I wouldn't bet on that lame 3-legged horse to win the race.
