As fds followers what can we do to prevent this

What can you do to prevent this? End things as soon as he says or do something you don't like. Don't sweep in under the rug, don't give second chances. When he agreed to do something and you see signs of chickening out then leave. When he keeps on stalling this saying hes not ready then leave. If he's ready to have you as a free chef and maid, if he's ready to move in with you, ready to be a girlfriend giving him the wife treatment, if he's ready to have sex with you but he's not ready to give you what you want then it's pretty obvious that he's just using you and wasting your time.

Remove yourself immediately, treat relationships like a house, your life is a house and if he's 3 months too late to pay the requirements you expect from them then it's time to evacuate.

And lastly, love men a little so that it takes a little to get rid of him when he no longer acts accordingly.
