How are you doing? Your issue is kinda complicated but can still be trashed carefully.
It is either your boss is in love with you which I see as being illicit if she is married already or there is something that is not too good about you that she doesn' t want her niece to be a victim of.
Whichever one, just try to read in between the lines and take things easy. You don' t want to lose your job because of her niece who happens to be your girl. Try to find a common ground to discuss with your boss if that is possible, and find out what is going on. You don' t want to do that during official hours but carefully chose the right time to do that. I hope that girl is ripe for a meaningful relationship and you are really serious with her, if not, you don' t have to go through all these, just take to your heels to protect your job.
Best of luck.

Hi kemisuga. I'm swept off my feet by ur response to the question, but I dont believe I'll be able to hold my breath if all what u said is true. U must be a book that must be read to fully appreciate it's content. With all modesty and sincereity of heart, may I get to know u pls?

Hi, it depends on the circumstance that led the girl to the act and also her opening up to u, cuz her confession does not automatically mean she will turn over a new leaf.It has happened to me before and eventually we broke up cuz the girl found it difficult to change.I'm not offering my own experience as a determinant for what will happen to u but it's better to learn from somebody else's experience.If u can forgive the girl, please do, but be sure of her repentance. I wish u guys best of luck.

I just met a girl and I'm really interested but I've not spoken up cuz of some things; 1.I'm ready 4 marriage but i'm afraid the girl is not yet ready cuz she is still going to school.2.Getting down with someone not funny to me.
