Nope. He's going to chase you. You're probably better off with different friends than him, even if it hurts a little now.

Bear in mind that with Will stay just as friends' Doesn't mean... The end. This means that with staying in touch, the heart doesn't know the difference in your mind that may now be made up to Say... I can never see him as more than friends anymore.
You both may stay in touch through text once in awhile and he may even want to meet up to hang out. It's your choice, your call but for now, don't wear your heart on your sleeve for even a minute wheni t may not be 'Broke up' altogether with his "EX," who may still have a softie spot for her and they could end Up... Talking again or making some sort of agreement much like the one he and you have agreed on.
Silence is golden for now and doesn't necessarily mean "So long."
Good luck. xx
