You're not going to get any different advice on this forum to what everyone said on the other one. They are right - this can not and must not go on.
You love this man because you are a loving person - because you have love inside you and you have given it to an unworthy object. He cannot love you back, however he pretends in between; you are his victim, not his partner. He does not need you, and you most emphatically do not need him. You will be much lonelier with him than without him in the years to come. Get away from him, and give yourself a chance to spend your love where it is wanted and deserved.
Anyway, very soon you won't be lonely, you'll have a lovely son or daughter to mop up all your spare love and give it to you back unconditionally. That's the most important thing in the world.
