Liz honey , you say he's cheating on his gf , the guys a cad , drop him and see if he comes running . I like the others advice to you about saying no too , of-course he's going to make you feel special , connected , and the only one when he wants sex . Have you also thought how it may be wrong what you're doing too , plaaying around with someone elses boyfriend , you knew he had a girlfriend love .
I would tread carefully , someone's going to get hurt , and it won't be him . x
