What are some signs to look for?

Edit: Thank you so much to everyone who responded so far! I’m recognizing many things from this list in my NVM ex, who I’m pretty sure love-bombed me in the beginning and then became emotionally abusive soon after I agreed to be official. I’ve given all of you upvotes.

This list can really help those ladies who are young or don’t have much relationship experience, so they don’t get blinded by all the attention in the beginning.
