Is it wrong?

My boyfriend & I have been together for a year & a half. We have been fighting a lot lately & decided that we needed time Apart. I left for a week. While I left, I had been talking to a friend I grew up with. We went out a few times & he was such a gentleman. Opened the door, payed for my dinner, carried on a conversation & was not pushy at all for other things. He made me feel the way a girl should be treated. My boyfriend & I are still taking time apart from each other. Is it wrong for me to be talking to him & going places with him? He doesn't have any intentions, that I am aware of.
