Hi Kitty, I hope you are feeling better today.
It seems to me you are feeling a bit guilty, which is OK becasue we all do from time to time, nobody adheres to all the rules, all the time. But a lot of what you say- esp being bisexual and not acting on it - seems to follow the prescribed path for Catholics. Youa re getting amrried in November yes? (Congratulations). It seems to me then, that if you ask God for forgiveness, you will be given it. The piece of apper might be lacking, but that's being rememdied and your beliefs in Marriage- the children you love, your love of your partner- are far moreintact than many a married religious person I know. The whole point of God, after all- God is forgiveness.
Now I am not a Catholic, and never could be. I'm really just starting to rediscover my Faith after a long time running from it. The answers I am slowly gaining are of the importane of the teacjings of Jesus, and taking faith from them. If what you do on thie earth is motivated by love and with notitntention of causing harm, you won't go far wrong imo.
Also re the marriage- the benefits of marriage for religion and catholicism are clear; its largely stable (I say alrgely, clearly its not always ), its for raising children of known genetic origin within your faith- you are doing all that.
