You wAnna have sexwith the devil WTF?
Well that's natural that he wants to have sex with you since you want to do the same with him. Why would he give up the chance to get anything with no strings attached. Do you want any strings attached? At least that's what he'll probably think since you know he has a girlfriend and that's what he'll probably try to use to push you aside. Don't fall for a guy that's in a relationship with another woman, if he wanted you just as bad he would be in a relationship solely with you. You can't settle for less than your best, there are too many men out there, and some that are so much better. You don't want to physically, emotionally, and spiritually entwine yourself with something that is not really what you want. Yeah, you might be interested in the physical aspect of a relationship with him but there is more than one side to it. Pain and hurt will be your result if you set yourself up that way. Do you really, in your hear have peace about this, or about this certain person. Plus if he is willing to cheat on his girlfriend and lie to her, what makes you think that any other action towards you will prove to be trustworthy. I hope you make a decision that will be best for you despite him. I hope this helps you. Thank you.
God Bless
