You can never be wrong when it comes to feelings, you just feel the way you do, regardless what is the cause.

When it comes to what ‘happened’, you will never know , since you weren’t there, who can you trust on telling the thruth and does it really matter?

The fact you both work together doesn’t make things easier.

2 things i can say for sure abt a relationship are: trust and accepting eachother the way you are , these are very (if not most) important.

The fact you felt hurt and foolish says a lot about your feelings about her, now find out how she really feels about you, wich you best do to look at actions / behaviour, not words.
