Would it be OK if I continue to attend services without an intention to convert? I am made to feel very welcome, but I am unsure if there is an expectation that someone like myself who attends all services has the intention to convert. I know that I can not receive any sacraments, but I am invited to partake of the blessed bread distributed after the Liturgy.
It's absolutely okay to attend services as a non-Orthodox with no intention to convert. You should know that traditionally, non-Orthodox were dismissed during the second part of the Liturgy (the Liturgy of the Faithful, i.e. the Eucharist); this is still practiced in monasteries, but a regular parish should have no problem. I know that there are a few non-Orthodox members at my parish that have been attending for years and years.
When I began attending Orthodox services, I stated my views very plainly. I was an atheist, and I had no intention of converting. When catechism classes started, I had shed most of my atheistic beliefs, but I still wasn't prepared to make any commitments and I told the priest this. He simply replied that there is no expectation, and that I was welcome to come to the classes to learn.
Of course, God converted me to the Faith when the classes ended on Easter of this year.
I would say that you should be open to the possibility of conversion, without any feeling of compulsion. You never know what will happen in your life, as I can attest. But let everything happen naturally, by God's will. I am sort of a rarity in that I jumped from a non-Christian tradition to Orthodoxy in only 1.5 years or so. For most people, the journey can be much longer, and doesn't always end at the Orthodox Church.
While I firmly believe that The Church is the fullness of the Faith, I also believe that as long as one is sincere and lives a life of prayer and repentance, God will take them where they need to be at the right time.
