you're right, you should not string this guy along if you're not sure if you aren't pshysically attracted to him. not to say looks are everything, but if there is some doubt about his looks it could be a dealbreaker. there are many guys i've found out myself that i wasn't all that attracted to in my life, but i did still have feelings for them as they treated me well. with your struggles too maybe you should get it out in the open first too so you aren't the hurt one if they can't accept you for who you are.good luck
