GTO, I agree w Newman. Hanging out at that time definitely sends the wrong signal. I think this guy is attracted to you. Otherwise he wouldn't be texting you. You can be open with him that you only want company/friendship, and then he can decide. I would have that conversation before spending time w him late at night.
I disagree w Newman's POV about dating. To me, dating is not just having fun. If you're dating, you're attracted to the person and are seeing him or her casually, but w romantic intentions. Sex or some form of physical intimacy is usually part of dating, especially after some time has gone by. I disagree w dating while separated bc it impairs your individual growth and does not let you objectively evaluate whether you want to stay in your M or not. That's my opinion...
