Well I cannot speak for all people and all relationships but in my opinion, no (if they was love, or at least genuine feelings between the two people that it). I broke up with the girl I was in love with and then we fell out of contact for a while (during that time I could "forget" about her) but eventually we got back in contact and started hanging out again on the regular (us two and two other friends with us as well). And well I'll put it like this, the third or fourth time hanging out things got a little physical between and now we date again lol. Of course I'm happy about this now but when we started hanging out and talking again I was intent on keeping the relationship on a just friend level.
So as far as I can tell, as long as there is consistent contact, the "just friend" thing won't last.
