depression

I have now been feeling like I am about to have my second outbreak and it has been a month since i found out. It is now making my thoughts wonder. And still of not knowing who gave it to me the person i been with for almost 2 months has been by my side but even still we are still tlkn and still have sex with just each other. Just im confused and lost.. He talks to other women and denies it and I mean he has been with me every day literally and works but i am not sure. I am foolish and just dnt want to be alone... Ughh im just the dumbest and he cooking us dinner and i am just sitting here like mood changed & im hurting on inside
