Hello K.,
Your family members and boss are partly correct about admission to the Sacraments, however, I believe that you can ask your pastor to bless your marriage, even if it is not performed in the Catholic Church. Before you make any decisions on whether or not to continue going to the parish, I highly suggest that you meet with your pastor. He can help answer questions that you have and address any concerns that you have about the suitability of the Catholic Church for you. Do you know what the word "Catholic" means? It means universal--it's for everyone because it is the one and only Church that Christ Himself established.
Is the reason that you are not having your marriage in the Church because of your concern for the expenses of having a church wedding? (I kinda thought that might be it since you mentioned about having to pay for it on your own and having a simple wedding.) A church wedding need not be a grand affair. Although it is recommended, you do not need to have a whole Mass with your wedding. You can simply have the Nuptial rite and have it as simple or grand as you desire. We got married straight out of college and my parish waived the fee that they normally charged and the music director very generously found musicians who were willing to perform at very little cost.
The process of returning to the Church is part of a spiritual journey, and it may be difficult at times, and sometimes you might not feel like you are on the right path, but I really do pray that you ask God for the strength to stay with it. I truly believe that your heart is in the right place, and that you long to return to the beauty of Christ's church. It is not necessary for you to come to full understanding and agreement all at once. It will take time--lots of time, but rest assured, that once you complete your journey home your fellow Catholics will rejoice with you in welcoming you home!
"Beloved, do not be surprised that a trial by fire is occurring among you, as if something strange were happening to you. But rejoice to the extent that you share in the sufferings of Christ, so that when His glory is revealed you may also rejoice exultantly"-1Peter 4:12-13
Blessings,
K.
** I'm suppressing my urge to reply to everyone who is bashing the Church but will only say that everyone who has left the Church (yes, it is difficult to be Catholic in a world that is so opposed to Catholicism) has rationalized their decision and can state their reasons for departure ad nauseum. No one ever promised us that following God would be easy and I think that the Catholic Church has a deep understanding of Christ's sacrifice and how we can participate in that redemptive suffering and sacrifice.**
