Afraid

How do you all deal? I got diagnosed 3 yrs ago after having been ceibate for 2 years. I told my ex and even though he stayed he abused me in every way possible. Now I was abstaining because I'm afraid to deal with anyone else for fear of rejection. I had sex(protected) with my ex fiance recently and I felt like shit because he knew and because he wasn't intimate at all I felt like the disease itself! No kissing no caressing. Just enough to get his. I didn't get moist or orgasm because I didn't feel like he was turned on because of it. Then the condom busted and he was all worried asking questions.
