I'm dating a guy, 38, I'm 36. How do I know he really is into me? Kind of weird situation..?

just quit with mr.craigslist guy and move on with a one lady man.cause,if that woman was close by his place.he will use both of you as much as he could,until he gets caught with either of you.He has to honestly commit all to YOU! why,even try to battle for his love while he still communicates with another lady.He has to change his way from not texting her back and move on with you.otherwise,you're being played like a puppet..
