relationship compatibility

I broke up with my boyfriend today because although he is a professing Christian, he is deep into false teachings and we are unequally yoked. I have been crying all night (I've been crying over this for days really). I feel that I want to ask God to show me if I was wrong to break up with him...

Is it time to let him go? I’m a v waiting for marriage but he says cohabitation is important to get to know the other person - am I being unreasonable and is he having a point? He says he’s looking for a woman with his views - do men who generally cohabitate believe in marriage at all?
