I don't know of churches that tell their members not to date. Then again, my church-going experiences have been limited; first, a simple Bible church; and now, my LCMS church. Neither one forbade dating.
I used to be in your shoes. I thought of myself as a lone wolf (hence the name) not meant to go to church. I had attended the Bible church here and there, but usually I stayed home on Sunday's. I then started researching and asking questions, found what I did and didn't like, what I did and didn't agree with, and eventually found the LCMS to be a great fit. I started attending the church in, I want to say, August, but by October I stopped going and was going through a tough time. It all started with me doubting that this was real; by this I mean, that I had found a church where I fit in well. I thought it was too good to be true. I really made myself feel that way, no doubt with the devil happily guiding me. I found myself digging deeper into my past and falling back into the world. October was a rough month. Thank God I snapped out of it, no doubt by the grace of God, with him kicking the devil to the side and taking control of my life. I've now been back at a church I truly love, in a faith and denomination I truly love, for a couple of months. I couldn't imagine trying to do things alone again. There's a church out there for everyone. You will find one that is right for you. Be proactive, eagerly hunt, do tons of research, and most importantly let God guide you. The reality is, you will never agree with everything, but you don't have to. Good luck!
