Thanks CB! By far the best advice i've gotten so far. Thank you, that puts my mind at ease.
What do you think would be a good way to say all that to him to maintain his distance, etc. without coming off as a jealous/ or insecure type?
Thanks Mano... as I mentioned dont tell him directly ... wait until he mentions this girl again, let him start the topic and then just casually say : well such people are so hard to avoid and manage why not sit a couple of seats away from her etc etc ...
Ensure you are not overdoing it in your advise to him... jsut mention it once and consider your job done .. rest , just trust him fully and dont start being suspicious if he isnt able to carry out the task immediately ... its just a matter of 2.5 months not like he is always going to be working with her ...
