The lover should no longer visit the priest since the priest is not helping him. So there is no point. There should be a point in doing things such as going to see a priest, a therapist, to a group, social gathering, etc. On the most general level, there are two types of goals one might have when one goes to such gatherings, meetings, appointments, and the like:

(1) to give of yourself
(2) to get some benefit for yourself
(3) both, above

In the case of social gatherings, ideally, you want (3). But in the case of seeing a priest, you are into (2). Since the priest does not help your lover, there is no point in going back to see him. Also, the priest is evil in that he attempts to withhold blessing from your lover. Blessings are very important to everybody and attempts to withhold blessings are evil.

You asked three questions:

1) What to do?

I have no idea whatsoever since you provided very little information. It seems that your main issue is lack of social acceptance of your r/s with your lover. These things vary very widely depending upon the sociodemographic situation, which you did not describe. It is one thing to have an affair in a small village where everybody knows one another, and another thing to have an affair in a metropolis where nobody gives a damn about others anyway.

2) How are you supposed to feel?

There is no such thing as "supposed to feel" - you feel what you feel; you can act or refrain from action based on what you believe that you are supposed to do, but it does not apply to feelings. That said, to the extent that you have SOME power over how you feel, observe yourself feeling differently and choose the feeling that is most satisfying to YOU and most conducive to having you enjoy your life.

3) who are you in the eyes of God?

I am not God but I will try to answer for God:

You are a human just like anybody else, with her desires, fears, conflicts, etc. No better or worse but just a human like anybody else.
