What to do please?

Her marrying you, may be a future thing for her?
And yet, from the sounds of things, you're not seeing her outside of work?

Oh yes you can see her outside of work.
In public places, with a chaperone / family member.

Yeah but I don’t think it would be sensible when our families don’t know that. I want to understand exactly why is it this avoidance from her side is occurring whilst we are at work. And whether or not there’s any signs or signals or she’s trying to give a message across yet I’m failing to understand?

Its only occuring bcs ur also avoiding her. Her confession has made things awkward bcs u havent said yes or no

This is madness!
You don't know each other as people.
You just know each other as work colleagues. And not very well at that, from the sound of things.
Get to know each other as people.
It's down to you to pave the way to the 2 of you getting to know each other as people.
Look at things from her point of view. Why should she marry you?

Well the thing is I need to deep down establish whether there’s feelings there for me or not because my feelings is clear for her and I told her this myself. I don’t want to be led or played on just by waiting for her. I mean I would wait for her but I would want to know yes I feel the same way as you do for me and then it only means one thing then.

If you were to marry her, would you feel as if you'd been lucky and had overachieved in this aspect of your life?
Now put yourself in her shoes. Do you think she'd want the same feeling?
What have you done to give her the feeling that she would have overachieved if she were to marry you?
What have you done to give her the feeling that she would have underachieved if she were to marry you?

If you remove the religious window dressing it sounds like after you initially said you liked each other you've then totally shut down and put your head in the sand, probably offending her or at least making her feel rejected. Nothing you're saying implies you intend to change this anytime soon?

When you say offending her what do you mean? And shutting down putting my head in the sand? And no there’s nothing for her to feel as though she’s rejected or something because I would love for this to work she herself said I’m a decent guy and it’s for the future.

Well that's what I'm saying, if you remove religion, this is basically just ghosting someone, in terms of dating game it's awful. Your priority seems to be to keep your distance and mind your own business and that's it? You say you want to know more about her feelings but you sound like the one keeping your distance?

Look I understand what you’re saying but I need to be respectful of where she’s coming from and I don’t want her to feel harassed or nagged about this matter. I want her to feel as though she has that respect from my side with space. If I do want to know more about her feelings or to why she does this my question to you is if I let’s say spoke to her baring in mind I just want to ensure there’s respect, space and no feeling of being harassed am I doing the right thing and two what should I do then?
