Men usually take sex as a sports,visualise a woman like a sexpot and take them for granted. They do not value woman chasity and almost regard them as a booty call.
When a dishonourable man treat you as a rebound or want nothing more than you,but just a booty call. You have to learn how to jeopardise this hazard in order to let yourself getting less hurt. A guy would never hurt you if they would treat you properly,with respect and most importantly, a value in their life.
When a guy say they need time to reconsider about their feelings with you. Forget about it, they are just making a plain excuse in avoiding this issue and also, preying for better targets out there, and you are unlikely to be one of them. When they call you out of the blue, without any notice, they just want a sleepovers with you,cuddles,sex with you and nothing more than that. So, please do not assume they are actually interested in you whereby they are just treating you as their passing time moments.
Nothing worth more than knowledge,because knowledge is power. A guy would actually be an honourable man if they actually see you as a human-being,treat you nicely,fancy you and shower you with more care,concern and love instead of treating you as a sex pot.
Basically, we are not kleenex in which we are use once and throw away. This theory is long existence in our logic because guys treated everything like their favourite sports game whereby they do not see the consequences it cause hurt, and more hurt.
