I'd say you're ok with reciprocating "love" if it comes to you first IE: hug, cuddle, etc.. Just don't be a walking doormat, you want a real R/M back and don't settle for less. Also, if things do turn around don't rush into things too quick. The reasons why are: you can feel unsatisfied and regret making up and just like now people can change their minds quick and often.
"Don't chase people. Be yourself, do your own thing, and work hard. The right people - the ones who really belong in your life - will come to you. And stay." ~ Will Smith
