In his mind, he has the power now because you've given it up. I never sleep with a guy who I intend to have a serious relationship with until I get a ring on my finger (if he meets the standards for a husband, that is). Only **** those with a nice body and who you don't intend to have a serious relationship with. Otherwise, have some self-control.
I will say that you screwed up in accordance to his reaction (not making you his girlfriend). You can try to do some damage control by distancing yourself. But I will say, don't have high hopes for this guy.
A strong woman takes advantage of help she can get from people around her but she doesn't rely on them for anything
She uses logic and manages her emotions
She offers help either because it is a business transaction or out of kindness. It is never because she hopes others will return the favour or out of fear of losing them
She has her own mind and thinks for herself and knows that she has to be the one who bears the consequences of her decisions
