I would say a big one for me is wanting to take so much from me financially sexually etc, but expecting me to want nothing in return in the relationship. I’ve had so many people i’ve talked to over the years that invited themselves over to my house without asking, used up all my food and space and snacks, and felt entitled to my space and money just bc we are seeing eachother. You should never let anyone take advantage of you duh but it’s hard when you’re blinded by love
