Asalam alaikum Sis,
I have been reading all of the posts here and there is some excellent advise being offered. Looks like its been a while since you saw him, but with a guy like this he doesn't respect women at all and certainly only see's you as an object of his lust. Sis, seems like he isnt harrasing you like before thats good, but from your last encounter seems like he is still after you and lusting over you. Don't beleive his stupid lies, he isn't going to just change, this is his personality and he doesn't seem to want to change. He will tell you anything to get you, but he is no better than a piece of dirt. You deserve a good muslim man who follows Islams teachings and this guy is not that guy.
Looks mabye attact initially but without a good character those looks don't even matter, he is ugly and disgusting inside.
Even if you guys got married, chances are that he wouldn't respect you and treat you well. Once he has you the challenge is over, and he would move on to another challenge.
Please Sis, take all the advise given here as very well meaning, and we all don't want to see our sister being abused in any way.
Take Care and inshaAllah you will be guided in what is best to do.
