i refuse to say anything hurtful to someone who is hurting. i know how you feel for i have compassion for the broken hearted.
this man is wounded, he has been in bad relationships. this has nothing to do with you, but because of this he doesnt want to get into another serious relationship.
when i was hurt badly i didnt want to get back into a serious or long term relationship because i didnt trust anyone.
you have to let him go so he can heal. usually some guys who has been trashed on, are in a rebound with the next person they get in a relationship with.
he shouldve been honest with you in the beginning of what he wanted. i beg you to be careful next time.
