Hi there! First think about why you might be holding back with telling her, is it her reaction that worries you or just that it`s a challenge for you communicate hard things? People talk to people at work all the time, so figure out why you really feel kind of guilty for talking to the lady. If its just that she is a nice person and pleasant, that`s a normal feeling. Could there could be underlying feelings you have that you might not be willing to admit to yourself and maybe that`s what`s causing the discomfort in you? You don`t have to answer any of this here, but you have to answer for yourself. Sometimes people want a chance of scenery and talking to a new person of the opposite sex helps, it doesn`t have to mean anything bad. It`s natural. Try not to beat youself up. You are doing the best you can and you sound like a wonderful man. You are talking things out and looking for solutions. Stay hopeful you will find the answer but make sure you do lots of self reflection look at your own feelings after you get input from others. You will find your way too be open. Be patient with yourself it takes time. good luck
