Gay and Catholic and Confused?

I was raised Baptist, and converted to Catholicism and really love the Catholic faith. I am gay, and I have a lot of guilt and shame from my ubringing. I am currently single, but want to date and get married to another man. My question is, should I stay in the Catholic Church and recieve Holy Eucharist while in a relationship with another man, or stop going to the Catholic Church when I meet someone and go to the Episcopal Church. I also want to know if going to an Episcopal Church on Wed. night for midweek Eucharist while being an active member of the Catholic Church is a bad thing. Please give me some advice if you can.
