baptism/chrismation/etc. should only be done for someone who wants to be an orthodox Christian.
it should never be done for the purposes of marriage (like you can 'fool' God!) but only for individual need and request.
you can only be remarried to your spouse if you are both orthodox, and definitely this is not an area on which you should put pressure on your spouse, who is on her own spiritual journey and who has a very important personal relationship with God.
so if you are orthodox and your wife remains catholic, this should still be considered a valid marriage, especially as you married in a church whose sacraments are recognised by the orthodox church.
you should certainly be allowed to be orthodox and have confession and take Holy Communion while your wife remains catholic and able to attend services with you (if she wants to) and not take Holy Communion.
there is no need to rush here; God knows both your hearts and loves you both greatly.
when i became orthodox (with my husband's permission), he remained protestant, and i have had no problems in taking Holy Communion because of this. i am in an oriental orthodox church (coptic), but from all i have read about eastern orthodox churches and from my experience with EO friends, the principle is the same in EO churches.
so i would suggest you discuss this with your priest again, and maybe ask another priest if you don't manage to understand each other on this issue, as putting pressure on a spouse to 'convert' and have a church marriage is not what an orthodox priest should normally do.
feel free to send a personal message if you wish, as i have met (in real life and on line) plenty of couples where only one is orthodox.
i am glad that thomas' story was so happy (sounds great!) and i pray that yours will be too, as you grow in love and patience.
