Welcome to PC! A number of things about your situation concern me. The reality is that we teach other people how to treat us, if you accept this now it will on a certain level become "okay" behavior in your relationship. This kind of careless sexual activity is how diseases are spread...stuff that ajax wont wash off that might even kill you! I would venture that somewhere in your mind you know all of these things, but somehow have trouble standing up for yourself and your best interests.I would start by kicking this loser to the curb and taking a good long look at myself and where I'm headed in life! make some good decisions for YOU! you'll feel empowered by doing whats best for you and the depression will leave.
