Most Helpful Guy
Be careful, he's in a honeymoon phase right now. All the sh*tty emotions of his stale ex-relationship suddenly got washed away by the endorphins and oxytocin overloading his system and he is literally high as a kite. You cannot trust these intense feelings to be long-lasting just yet.
However, there's no reason not to jump into the relationship boat with him. Just be aware that this "crazy in love" phase is just that - a temporary state that is highly likely to pass. You will eventually bore of seeing each other every. single. day. and the things that bother you will begin to stand out more.
Love is what follows when people stick together through many honeymoon and cooldown phases.
Go ahead and get official if you feel comfy with it, but be aware that you are the "rebound." It's not game over, just be conscious of the fact that emotions are taking control right now, and you'll need to adjust as the relationship moves forward : )
Good luck to you!1
